Fidget spinner

A fidget spinner is a small, handheld toy featuring a central ball bearing surrounded by a multi-pronged frame, typically made of plastic or metal, that allows it to rotate rapidly when flicked by the fingers for entertainment or stress relief.^[1] The device balances weight across its arms to maintain smooth, prolonged spins, often lasting up to several minutes with a single flick, and is held in place by pinching the bearing between the thumb and forefinger.^[2] Invented in the early 1990s by Catherine Hettinger, a Florida-based chemical engineer, the fidget spinner originated as a simple diversion while Hettinger was suffering from myasthenia gravis, an autoimmune disorder causing muscle weakness that limited her ability to play actively with her young daughter, who had chronic fatigue.^[3] Hettinger filed a U.S. patent for the toy in 1993, which was granted in 1997 as a thin, disc-like plastic structure with a central dome for finger placement and a skirt for rotational balance, intended for amusement and potentially aiding in habits like quitting smoking. However, unable to afford the maintenance fees, the patent lapsed in 2005, allowing others to develop and commercialize variations, including the bearing-equipped designs that became widespread.^[3] The toy surged to global popularity in 2017, becoming a viral sensation among children and adults alike, with millions of units sold and dominating toy sales charts on platforms like Amazon, where spinner variants occupied much of the top rankings by mid-year.^[3] Marketed initially for therapeutic benefits, such as improving focus for individuals with attention-deficit/hyperactivity disorder (ADHD), autism, or anxiety, fidget spinners were promoted as tools to channel restless energy into repetitive motion.^[1] Research on fidgeting, including a 2015 study by Julie Schweitzer at the University of California, Davis, found that physical movement enhanced cognitive performance in children with ADHD during attention-demanding tasks, lending some scientific credence to these claims, though evidence specific to spinners remains limited.^[4]^[5] Despite their appeal, fidget spinners faced controversy, with many schools banning them as classroom distractions, while others embraced them as sensory aids for neurodiverse students.^[1] The craze peaked briefly before fading, but the toy's legacy endures in broader fidget tool trends, influencing designs like pop-its and squishies, and highlighting the role of social media in propelling short-lived fads.^[3] As of 2025, the fidget spinner market continues to grow with renewed interest in premium and innovative variations.^[6]

Design and Mechanics

Physical Components

A standard fidget spinner features a central ball bearing that serves as the pivot point, enabling smooth rotation around a fixed axis. This bearing is typically a 608-size model with dimensions of 8 mm inner diameter, 22 mm outer diameter, and 7 mm width, or the smaller R188 variant measuring 1/4 inch inner, 1/2 inch outer, and 1/8 inch width. Materials for the bearing include chrome steel for basic models, stainless steel for durability, or ceramic hybrids (with ceramic balls and steel races) for reduced friction in premium versions.^[7]^[8]^[9] The weighted lobes, or arms, extend from the central bearing and are usually configured as 2 to 4 prongs, with 3 being the most common design for balance. These arms are constructed from lightweight plastic in entry-level spinners for affordability, or denser metals such as brass, aluminum, titanium, stainless steel, or copper in higher-end models to increase momentum. Each arm typically weighs between 10 and 50 grams, depending on the material—plastic arms around 10-20 grams, while metal ones like tungsten inserts can reach 45 grams per lobe for enhanced performance. Composites may also be used for a balance of strength and reduced weight.^[10]^[11] Overall, fidget spinners measure an average diameter of 7 to 10 cm and thickness of 1 to 2 cm, though shapes vary from triangular to circular or even multi-pronged configurations like shurikens. Consumer variants often incorporate aesthetic or functional add-ons, such as LED lights embedded in the arms for illuminated spinning effects or glow-in-the-dark phosphorescent coatings on plastic surfaces.^[12]^[13] Assembly typically involves a press-fit or snap-fit method to secure the central bearing into a molded hub, with arms attached via screws or integrated molding for stability. In some designs, weights are glued or slotted into place, while premium models may use threaded connections for modularity. Entry-level plastic spinners, often mass-produced and weighing under 50 grams total, contrast with premium metal versions like engraved brass or titanium ones exceeding 100 grams, which offer customizable engravings and superior heft.^[14]^[15]^[16] These physical elements collectively allow the device to spin freely when flicked, supporting its role as a handheld toy.^[7]

Principles of Operation

A fidget spinner operates on the principle of rotational motion, where a user's finger flick applies a torque to the central bearing, imparting initial angular momentum to the device. This angular momentum, defined as L = I \omega, where I is the moment of inertia and \omega is the angular velocity, sustains the rotation of the weighted arms around the bearing.^[17]^[18] The rotation gradually slows due to dissipative forces, primarily friction within the bearing and air resistance on the spinning arms, leading to an exponential decay in angular velocity. For quality fidget spinners, this results in typical spin durations of 1 to 3 minutes under normal conditions.^[18]^[19] The decay can be modeled by the equation

\omega(t) = \omega_0 e^{-\gamma t},

where \omega_0 is the initial angular velocity, \gamma is the decay constant, and t is time. This form arises from Newton's second law for rotation, \tau = I \alpha, with angular acceleration \alpha = d\omega/dt. For viscous frictional torque proportional to velocity, \tau = -b \omega (where b is a damping coefficient), substituting yields I d\omega/dt = -b \omega, or d\omega/\omega = -(b/I) dt. Integrating both sides from initial conditions gives the exponential solution, with \gamma = b/I.^[17]^[18] Several factors influence spin performance and the value of \gamma. Bearing quality is paramount; ceramic bearings exhibit lower friction coefficients than steel ones, enabling longer spin times—for instance, hybrid ceramic bearings can achieve over 1.5 minutes compared to under 1 minute for standard steel bearings in controlled tests.^[20] Balanced weight distribution across the arms minimizes wobbling and energy loss from uneven moments of inertia, promoting smoother and more prolonged rotation.^[21] Environmental factors like high humidity can degrade lubrication by promoting condensation and corrosion within the bearing, increasing frictional losses.^[22] When a spinning fidget spinner is tilted while held at one arm, it exhibits gyroscopic precession, a phenomenon where the axis of rotation shifts perpendicular to the applied torque due to the conservation of angular momentum. This effect arises because the torque from gravity or manual tilt attempts to alter the spin axis, but the device's angular momentum vector precesses around the new direction rather than flipping immediately.^[18]^[23]

History

Origins and Invention

The fidget spinner originated in the early 1990s as a therapeutic device conceived by Catherine Hettinger, a chemical engineer from Orlando, Florida. In 1993, while battling myasthenia gravis—an autoimmune disorder causing muscle weakness—Hettinger found herself unable to engage in active play with her seven-year-old daughter, Sara. To provide a low-effort activity, she invented a simple spinning toy that could be balanced and rotated on a finger, allowing her daughter entertainment without requiring Hettinger's physical exertion.^[24] This concept led to the filing of a patent application for a "spinning toy" on May 28, 1993, which was granted as U.S. Patent No. 5,591,062 on January 7, 1997. The patented design featured a central dome structure attached to a flared skirt made from molded plastic, enabling it to spin smoothly on a finger or stick for amusement.^[25] Independently, in the early 2010s, Scott McCoskery, an IT professional from Suquamish, Washington, developed a similar but distinct fidget device to address his own habits of restless hand movements during prolonged meetings. After years of fidgeting with pens and pocket knives, McCoskery prototyped a metal spinner in 2014 to channel his distractions more discreetly. The first commercial version, known as the "Torqbar," a weighted bar design with a central ball-bearing hub for extended spin times, saw its initial sales in September 2015. McCoskery's design was produced in limited quantities through his company, MD Engineering, initially for personal and small-scale use related to focus and anxiety management.^[26]^[27] Prior to 2017, both Hettinger's and McCoskery's inventions remained obscure, with no significant market presence or public awareness. Hettinger's patent lapsed in 2005 after she could not afford the $400 renewal fee amid unsuccessful attempts to license the toy, leading to its entry into the public domain. Meanwhile, McCoskery's Torqbar saw only niche production, hand-built in his garage without widespread distribution. The two designs differed notably: Hettinger's was a compact, disc-like form emphasizing simplicity, while McCoskery's featured a linear bar configuration for enhanced balance and grip.^[3]^[26]

Patent Developments

The development of patents related to fidget spinners reflects a fragmented intellectual property landscape, with early filings predating the toy's viral popularity and later ones attempting to capture specific design and functional innovations. In 1997, Catherine Hettinger received U.S. Patent No. 5,591,062 for a "spinning toy," described as a disc-shaped device intended to spin on a finger or stick using propulsion, which differed significantly from the modern fidget spinner's multi-pronged structure and central bearing for handheld rotation.^[25] This patent expired in 2005 after Hettinger failed to pay the renewal fee of approximately $400, leaving the basic concept in the public domain well before the 2017 boom.^[28] As prototypes gained traction online in 2016, patent applications surged, with inventors seeking protection for refined designs amid rising interest. For instance, David Allen Pavelsky filed for a design patent on November 29, 2016, which was granted as U.S. Design Patent No. D801,440 on October 31, 2017, covering a three-pronged fidget spinner with a central ball bearing for finger-based spinning.^[29] Similarly, Michael Scott McCoskery, who developed early prototypes in 2016, submitted a provisional patent application on May 11, 2016, followed by a utility patent application in May 2017, resulting in U.S. Patent No. 9,914,063 issued on March 13, 2018, which focused on the bearing mechanism and body configuration to enable prolonged, balanced spinning in the user's hand.^[30] This influx of filings in late 2016 and early 2017 highlighted opportunistic efforts to claim aspects of the toy as it transitioned from niche handmade items to mass-market potential.^[31] Patent disputes centered primarily on attribution rather than enforcement, with media claims portraying Hettinger as the singular inventor debunked due to fundamental design discrepancies—her 1997 patent lacked the radial arms and embedded bearing central to contemporary fidget spinners.^[32] No major infringement lawsuits succeeded by 2025, as the expired Hettinger patent and narrow scope of later designs like Pavelsky's and McCoskery's limited viable claims against the diverse array of products flooding the market.^[33] The patent landscape's weaknesses fostered an open market post-2017, as lapsed protections and the toy's simple mechanics allowed widespread replication without legal barriers, particularly enabling low-cost knockoffs manufactured in China that dominated global sales and undercut original creators.^[26] This proliferation underscored the challenges of protecting utilitarian toys in a fast-moving consumer trend, where rapid imitation outpaced intellectual property safeguards.

Uses and Applications

Therapeutic Benefits

Fidget spinners have been promoted as therapeutic tools to provide tactile stimulation for individuals with attention-deficit/hyperactivity disorder (ADHD), autism spectrum disorder, and anxiety, with the intent of aiding focus by channeling excess energy and reducing hyperactivity through repetitive motion. The devices allow for discreet fidgeting, enabling users to engage their hands without significant disruption, which aligns with broader principles of sensory integration therapy.^[34] The purported mechanisms behind these benefits involve fidgeting as a form of self-regulation, where the sensory input from spinning the device helps modulate arousal levels and sustain attention, particularly in neurodiverse populations. A 2015 study published in the Journal of Abnormal Child Psychology found that hyperactive movements, akin to fidgeting, served as a compensatory mechanism that enhanced neurocognitive functioning and concentration in children with ADHD during demanding tasks.^[35] For adults with anxiety disorders, users have reported stress reduction through the distraction from rumination and the calming effect of rhythmic motion, though these accounts are largely anecdotal and supported by preliminary observations in occupational therapy contexts.^[34] Fidget spinners are particularly valued among neurodiverse individuals, with many parents and therapists noting their role in daily management of symptoms related to ADHD and autism. A 2023 study of parental perspectives found that parents of autistic children perceived fidget spinners and other fidget toys as more beneficial for their children compared to parents of neurotypical children.^[36] A 2021 study also showed that fidget spinners increased on-task behavior in second-grade students with ADHD during classroom activities.^[37] Despite these claims, empirical evidence for the therapeutic efficacy of fidget spinners remains limited and mixed, with several studies highlighting potential drawbacks. Research from 2017 to 2020, including a systematic evaluation in the Journal of Attention Disorders, demonstrated that while fidget spinners initially decreased gross motor activity in young children with ADHD, they ultimately impaired attentional functioning and on-task behavior during classroom interventions.^[38] A 2017 review in Current Opinion in Pediatrics concluded there was no rigorous scientific support for the marketed benefits in managing anxiety or hyperactivity, emphasizing the need for more controlled trials.^[39] These findings suggest that benefits may vary by individual and task complexity, with some evidence of improved fine motor control in less demanding activities but overall inconsistent outcomes for broader therapeutic goals. In clinical settings, fidget spinners have been used in therapy sessions for autistic children to support sensory processing and motor skill development, based on reports from parents and occupational therapists. Such applications underscore their potential as supplementary tools in personalized interventions, though they are not recommended as standalone treatments.

Educational and Productivity Uses

Fidget spinners have been incorporated into classroom settings as discreet focus aids for students without diagnosed conditions, allowing them to channel minor restlessness into subtle hand movements that support sustained attention during lectures and reading activities. Educators report that these tools can help typical students maintain engagement by providing a low-profile outlet for energy, particularly in environments requiring prolonged sitting. For instance, in mainstream classrooms, teachers have observed improved concentration when spinners are used quietly under desks, aligning with broader strategies for sensory regulation in educational spaces.^[40]^[41] In professional workplaces, fidget spinners serve as stress-relief devices for individuals such as programmers and artists, who use them during meetings or brainstorming sessions to alleviate tension without disrupting group dynamics. These tools fit seamlessly into office culture, often appearing as part of desk accessory collections by the early 2020s, promoting brief mental resets amid demanding workflows. Professionals note that spinning a fidget spinner can enhance clarity during repetitive cognitive tasks, such as coding or sketching iterations.^[42]^[43] Research from 2018 indicates that fidget spinners can yield minor improvements in fine motor control among healthy adults, potentially boosting performance in repetitive tasks by refining precision and reducing deviation in controlled movements. A study involving spiral-tracing exercises demonstrated statistically significant enhancements in motor accuracy after short-term use, suggesting a practice effect that supports productivity in detail-oriented work. Subsequent investigations in healthy adults have shown sustained gains in processing speed and attention, further underscoring their role in everyday cognitive enhancement.^[44]^[45] Adaptations like quiet-spinning models, featuring ceramic bearings or enclosed designs, have made fidget spinners suitable for shared office and classroom spaces, minimizing noise while preserving functionality. These variants allow users to maintain focus without drawing attention from colleagues or peers. Following the 2017 popularity surge, fidget spinners evolved into components of STEM education kits, where students construct and test them to explore physics principles such as moment of inertia, angular momentum, and rotational balance. Educational resources from organizations like Flinn Scientific provide hands-on challenges that integrate spinner design with measurements of spin duration, fostering conceptual understanding of mechanics.^[46]^[47]^[48]^[49]

Popularity and Cultural Impact

The 2017 Boom

The fidget spinner's popularity exploded in 2017, with viral spread accelerating from April as users shared trick tutorials and challenges on platforms like YouTube and Instagram, transforming the niche toy into a global sensation.^[50] By early May, online searches and sales had surged dramatically, with the toy accounting for 17% of all U.S. online toy purchases on peak days.^[51] An estimated 50 million units sold worldwide in the first half of the year alone, peaking at millions per week amid overwhelming demand that outpaced supply chains.^[52] Celebrity endorsements amplified the hype, with figures like Kendall Jenner posting about their use, while major media outlets fueled the frenzy; NPR proclaimed it the "must-have toy of the year" in a May feature, and CNN covered the fad's rapid rise among children and adults alike.^[53] ^[54] ^[55] This coverage, combined with organic social sharing, propelled the toy from obscurity to a $500 million global market that year, predominantly driven by low-cost imports flooding retailers.^[56] The boom manifested in cultural phenomena like "spinner tricks" videos, which proliferated on YouTube and garnered hundreds of millions of views collectively by mid-2017, showcasing feats from basic spins to elaborate stunts.^[57] Fidget spinners became fixtures in schools, where they invaded classrooms despite emerging bans, and in offices, where they served as impromptu stress relievers for professionals.^[57]

Global Reach and Media Influence

The fidget spinner phenomenon extended rapidly beyond its initial surge in the United States, achieving widespread adoption across Europe, Asia, and Australia by mid-2017. In the United Kingdom, the toy's popularity led to classroom bans in numerous schools as early as May 2017, with authorities citing distractions and safety concerns, culminating in Trading Standards seizures of defective units by June 2017. Similar restrictions emerged in Australia, where educators reported interference with learning environments, prompting widespread prohibitions in educational settings. In Asia, China emerged as the primary manufacturing hub, producing vast quantities that fueled global distribution, while Japanese companies adapted the design with high-precision bearings to create longer-spinning versions, appealing to local interests in craftsmanship and appealing to consumers seeking premium variants.^[58]^[59]^[60]^[3] Global media outlets played a pivotal role in amplifying and sustaining interest in fidget spinners, framing them as a fleeting yet captivating fad. The BBC extensively covered the trend, highlighting its origins in stress relief for conditions like ADHD before its transformation into a playground sensation, with reports on bans and safety issues drawing international attention in 2017. Post-2020, platforms like TikTok revived the toy through influencer-driven content, where creators shared nostalgic tricks and custom designs, contributing to a renewed wave of engagement among younger audiences. This media evolution helped transition fidget spinners from a short-lived craze to a persistent cultural touchstone.^[61]^[62] Fidget spinners integrated into broader pop culture through memes, music videos, and niche communities, embedding them in global social narratives. Parody songs and videos, such as the 2017 YouTube hit "I Love Fidget Spinners" by Guava Juice, which garnered millions of views, satirized the obsession while boosting visibility. Memes proliferated on social platforms, often juxtaposing the toy's simplicity with everyday absurdities, further cementing its meme-worthy status. By 2025, a resurgence occurred within everyday carry (EDC) communities, where enthusiasts at events like gaming conventions showcased metal and modular variants for their tactile appeal and stress-relief utility, maintaining niche popularity amid evolving toy trends. In 2017 alone, global sales reached millions of units, with China exporting substantial volumes to meet demand across continents.^[63]^[54]^[64]^[65]

Controversies and Regulations

Safety Issues and Bans

Fidget spinners have been associated with several physical safety hazards, primarily affecting children. The U.S. Consumer Product Safety Commission (CPSC) issued warnings in 2017 highlighting choking risks from small detachable parts, such as bearings or lobes that could break off during use, particularly for children under three years old.^[66] Additionally, light-up models containing lithium coin cell batteries posed burn risks if ingested, as these batteries can cause severe internal injuries to the esophagus and intestines within hours.^[67] Reports of battery-related fires emerged in 2017, with at least two documented cases of electric fidget spinners igniting during charging due to faulty lithium-ion batteries, similar to issues seen in other unregulated electronic toys.^[68]^[69] Emergency room visits related to fidget spinner injuries peaked in 2017, driven by the toy's widespread popularity, which led to increased misuse such as throwing or high-speed spinning near the face. Notable incidents included eye injuries from sharp edges or flying parts, with cases reported of corneal abrasions and near-blinding pokes in children across the U.S. and Australia; the CPSC noted multiple such reports prompting investigations.^[70] Choking cases also surfaced, including a Texas girl who swallowed a spinner bearing and required emergency surgery to remove it from her esophagus.^[71] Other injuries involved lacerations from broken components or fingers getting trapped in the spinning mechanism, leading to hospital admissions.^[72] In response to these hazards and distractions in educational settings, numerous U.S. schools implemented bans by mid-2017. A survey of the top 200 high schools found that 32% had prohibited fidget spinners, affecting institutions in over 20 states including California, New York, Kentucky, Massachusetts, and Minnesota, citing disruptions to learning and potential injury risks during use.^[73]^[74] Airline policies also addressed loose spinners; while generally permitted in carry-on and checked baggage by the Transportation Security Administration (TSA), incidents of modified spinners resembling weapons led to confiscations, and passengers were advised against using or throwing them in-flight to prevent hazards.^[75]^[76] Regulatory measures followed suit internationally. In the European Union, 2017 enforcement of the Toy Safety Directive (2009/48/EC) and standards like EN 71-1 led to multiple recalls of non-compliant fidget spinners imported from China, primarily for chemical risks, choking hazards, and battery issues; the European Commission's Rapid Alert System for Non-Food Products (RAPEX) documented 11 cases, including models with loose button batteries and sharp edges.^[77]^[78] In the U.S., the CPSC oversaw voluntary recalls of specific models, such as keychain spinners violating small parts regulations, reinforcing guidelines that all spinners meet federal toy safety standards.^[79]

Scientific Evaluations

Scientific evaluations of fidget spinners have primarily focused on their purported role in managing attention-deficit/hyperactivity disorder (ADHD) symptoms, with research from 2017 to 2020 revealing limited to no significant benefits. A 2017 review in Current Opinion in Pediatrics concluded that there is no peer-reviewed evidence supporting fidget spinners' ability to improve concentration or provide therapeutic value for children with ADHD, emphasizing that claims of such benefits remain unsubstantiated.^[80] Similarly, a 2018 classroom-based study at Florida International University involving young children with ADHD found that fidget spinners worsened attentional functioning, increasing rule violations related to inattention during structured activities, while offering only transient reductions in hyperactivity that did not persist over time. These findings suggest that fidget spinners may heighten distractibility rather than mitigate it in educational settings for this population.^[81] Research on cognitive impacts has yielded mixed but predominantly cautious results, indicating potential short-term gains in focus for some tasks but risks of long-term impairments. A 2019 experiment published in Applied Cognitive Psychology demonstrated that using a fidget spinner during a video lecture led to increased attentional lapses, poorer judgments of learning, and significantly impaired memory performance on a subsequent recall test among undergraduate participants, suggesting interference with cognitive processing rather than enhancement.^[82] Spinner-specific studies reported no overall improvement in on-task behavior for elementary students with ADHD, reinforcing concerns about divided attention.^[81] Broader critiques highlight the disconnect between marketing hype and empirical reality, with systematic reviews underscoring minimal therapeutic value beyond placebo effects. A 2024 meta-analysis of single-case design studies on fidget devices, including spinners, found highly variable effects on academic and behavioral outcomes (Hedges' g ranging from -2.98 to 1.15), with an overall small effect size indicating negligible benefits for attention or self-regulation in children with ADHD, attributing much of the perceived efficacy to expectation biases rather than mechanistic advantages.^[83] This aligns with expert consensus that the toys' popularity outpaced rigorous testing, leading to overhyped claims without substantial clinical backing. Despite predominant skepticism, some positive findings emerge for non-clinical populations, particularly regarding minor anxiety reduction.

Market and Evolutions

Commercial Production and Sales

Commercial production of fidget spinners is predominantly centered in China, where factories in regions like Shenzhen rapidly established an industrial chain within months of the toy's 2017 popularity surge, producing the vast majority of global supply.^[84] Chinese manufacturers capitalized on existing toy production infrastructure, enabling quick scaling to meet international demand from retailers and e-commerce platforms.^[85] Global sales peaked in 2017, with millions of units sold amid the fad's height, accounting for up to 17% of all online toy sales in the United States at the time.^[51] The market experienced a sharp decline post-2017, stabilizing at approximately USD 129 million as of 2024, with projections estimating growth to USD 175 million by 2033 at a compound annual growth rate (CAGR) of around 3.2%.^[86] E-commerce channels, particularly Amazon, drove a substantial share of sales, comprising 60% or more during peak periods due to the platform's dominance in toy distribution.^[87] Key players in the market include brands such as Antsy Labs, creators of the Fidget Cube, which offers a range of fidget toys including spinners.^[88] High-volume production has contributed to lower retail prices that fell from USD 10–20 per unit to as little as USD 1.^[89] This cost reduction supported sustained manufacturing despite fluctuating demand.^[90]

Modern Variations and Trends

Since the mid-2010s, fidget spinners have evolved beyond their initial plastic designs into premium everyday carry (EDC) items, particularly metal variants crafted from durable materials like titanium for enhanced longevity and tactile appeal. These EDC-focused spinners often feature engravings for personalization, appealing to collectors who value precision machining and portability in daily use.^[91]^[92]^[64] Technological integrations have introduced smart fidget spinners equipped with motion sensors and Bluetooth connectivity to track spin duration, speed, and patterns via companion mobile apps, transforming them into interactive wellness tools for stress monitoring. Such app-integrated models emerged prominently in recent years, with features like biofeedback gaining traction among users seeking data-driven fidgeting experiences.^[65]^[93]^[94] Contemporary trends reflect broader integration within the fidget toy ecosystem, where spinners are combined with elements like Pop Its to offer hybrid sensory experiences that merge spinning motion with tactile popping mechanisms. These 2-in-1 designs, such as pop-it spinners, provide dual functionality for anxiety relief and have become staples in sensory toy collections. The EDC segment, including spinners, has seen a resurgence in 2025 among collector communities, driven by premium materials and customization, contributing to the overall fidget toys market reaching approximately $7 billion in value.^[95]^[96]^[6] Innovations emphasize sustainability, with eco-friendly spinners made from biodegradable plant-based plastics that decompose naturally, reducing environmental impact compared to traditional petroleum-derived materials. Customizable 3D-printed versions further democratize design, allowing users to create personalized spinners using open-source platforms like Thingiverse, where parametric models support adjustments for size, weight, and aesthetics via home printers.^[97]^[98]^[99] In niche applications, fidget spinners have revived as gaming peripherals, including thumbstick extensions and controller attachments that attach directly to gamepads for added grip and fidgeting during extended play sessions, aiding focus without interrupting gameplay. The broader fidget toys market, encompassing these evolutions, is projected to grow to $19.56 billion by 2031, fueled by rising demand for multifunctional and therapeutic designs.^[100]^[101]^[102]
