One feature that can be overlooked at first is texture. Surface texture will change the feel in the user’s hand and will have a direct effect on the kind of tactile feedback the design will provide. Relying than have a clean smooth and frictionless surface will allow much easier surface traversal. However a textured pattern will have a more engaging feel response with tactile feedback. Even minor design changes can drastically change the feel and engagement of a design.

Resistance to motion is one of the factors that a user will determine if they can be engaged. Having too loose of a resistance will make motion feel uncontrolled and clunky while having too much will make the interaction frustrating and feel negative. Having a nice resistance to the motion will provide a good feedback response without having to exert a large amount effort.

When designing a product shape and grip have to be balanced equally. An interesting design will ultimately fail if it is uncomfortable over time. Things like edges curvature and proportions all make a design more aesthetically pleasing while improving comfort and functionality. With larger designs more compact models are structurally stable while also improving the overall portability of the design.

When utilizing a 3D printer users have a lot of say over the functionality of a design. Users can alter things like layer height and how fast the printer operates to affect various aspects of a design. A lot of a toy’s motion and usefulness comes down to a user’s infill settings. For a design that maintains the same shape changing the infill and weight will have a noticeable effect on the toy’s motion.

Texture grip resistance and a lot of things that are beyond the physical appearance of a design are a focus of the most popular 3D printed fidget toys. These things add to a design a feeling of satisfaction and comfort to a user while also improving the functionality of the fidget toy.

Think about when you will use the toy. At work you will want something that is quiet and smooth. 3D printed fidget toys can have designs that give you options for different toys. Desk toys are nice because you can keep them on your desk and take them out during breaks.

Class is similar to work. You want something that is quiet but can be used repeatedly. Toys that have soft tactile feedback are nice because class and work are built around thinking. These kinds of toys give something for your hands to be doing but won’t take away your focus.

Being out and about creates the need for a toy that is light and portable. Other toys will be hard to carry but can be used easily. Toys that collapse can be stored easily. Things that used to be solid can be stacks which means your toy can be as small as a pen. High quality 3D printing won’t easily deteriorate with different usage like a toy being carried or fit into your backpack.

Sound can also add to the experience. There are people who enjoy satisfying clicks with a tactile feedback mechanisms. Others prefer a more quiet approach. How much feedback and interaction a person wants also depends on their environment. A mechanism that is enjoyable at home can be inappropriate to use at work or in a public space.

Fidget toys can also be used with materials of different stiffness. Firmer materials can imply stronger feedback movement and structure toward the toy. On the other hand materials that are a bit more flexible can offer comfort during prolonged use especially when a person wants a more fidgety experience.

Using 3D printed fidget toys that fit into a daily routine can help with Design preferences. The right toy can enhance focus in distracting or dull meeting or classroom habits that people have.

For different sensory engagements some fidget systems have different designs. Some provide a series of clicking motions and serve to provide a satisfying sensory experience while engaging for rhythmic sensory control. Other systems use smooth textures for the user and allow the user to transition motions seamlessly through their fingers. These systems also serve to provide a satisfying experience for repeated motion. Also some systems utilize a spinning mechanism to provide motion with a texture to the system.

For customizable printed systems experiences can be created for specific systems. Silent systems help minimize distractions. Users of these systems can choose a texture to suit them the best. Compact and more durable systems are also suitable for traveling and commuting to provide engagement for the user while taking up space. At users’ preferences these systems can be adjusted and experimented by bending or changing the resistance of the system. With these adjustments tools for fidgeting can serve to help with concentration more effectively.

Being purposeful can get technology to work with productivity instead of against it. Opt for distraction resistant tech consider quieter design tech and assess tech for the ability to focus vs. distraction of attention. The objective is not to create constant movement and fidgeting but to incorporate sensory experiences that work with daily activities.

When designing for the first time you should start with a simple concept. Fidget toys can be small and simple such as a click fidget a fidget ring or something like a fidget disc. The goal with the first project should be to understand how to have movement and shape complement each other and not be constrained by a complicated model.

For the next step choose a CAD program that is designed for beginners. Tinkercad is a useful program for forming small shapes to create and edit them and as your skills become more developed programs like Fusion or Onshape allow greater control and more sophisticated design. For the first step you should sketch something and then use the same shapes to form a small design. The CAD program should have the shapes you want available.

When forming moving parts it is necessary to consider ‘tolerances’. Tolerances refer to the spacing you leave so components can move freely after being printed. When the tolerances are too small parts can chemically weld to each other during the printing process. A good starting point can be a 0.2 to 0.5 mm spacing ( of ‘clearance’ ) although this can depend on your printer.

Some common mistakes new designers will make is placing too many details on parts leading to poor printing having walls which are too thin and lead to easy and instant breaking and having moving parts which are too complicated leading to excessive and unnecessary frustration. Often the greatest results come from the simplest designs.

Printing settings change the way the object moves and functions. For example using a smaller layer height means a smoother surface but higher infill means more weight and a stronger print. Also speed and accuracy change in relation to each other. A good first step is to find a midline value for infill and print speed or layer height.

Design and print the first iterations then use them to change and improve movements add flexibility and change texture. Think of this as your first design improvement; however most of the learning happens while you are iterating improvements.

One of the major aspects that can attribute to that satisfying control is the tactile feedback which is the sensation that your fingers feel as you interact with the object. When an object has a good balance of movement and tactile feedback you will almost always feel some sort of comfort or focus. For instance a button that clicks with some noticeable resistance will always feel better than a button that moves with so little resistance or even a loose button.

Some 3D printed fidget toys are engineered the right way to provide sensory feedback by having resistance and the ability to move and providing the ability to perform repetitive movement. These toys are engineered to give a sequence of small responses which fidgeters will find very satisfying.

Of course the design of a movement always accounts for texture. the sensation that your fingers feel as you interact with the object and the ability to perform that movement repetitively. Some fidget toys are so engineered in that way that they are able to provide a movement and a resistance that people will find very satisfying.

Mechanisms are important too. Spinners use little energy and create constant movement so they’re good for quick fidgeting. Clickers give feedback with movement that starts and stops. Pieces that create linked movement are calming due to the repetitive motion.

Assembling these pieces effectively will improve the experience for the user. Things that are too resistant are frustrating to users and things that are too flexible are unresponsive and overall cheap. Designers try to achieve a balance between how much someone has to do and the prize gained from doing it.

The most satisfying fidget toys stop working and the satisfaction is due to their mechanisms creating small repeatable movements that feel natural when being fidgeted with.

3D printed fidget toys can help new designers find issues with their printers. Moving parts can help find mistakes with printer calibration and settings. Luckily adjusting a few settings can result in a big improvement.

The first setting you want to play with is layer height. For beginner designs a setting of 0.2 mm is good. It’s a good setting in terms of print time and quality. If you lower the layer height to 0.12 mm you get a smoother surface but at the cost of longer print times. If you increase layer height it can decrease the time to print but make moving parts feel rough.

The second is infill. For fidget toys you actually want to aim for a lower infill of around 10–20% so they stay light and allow the toy to be played with. A higher infill actually makes toys heavier and doesn’t help them at all.

Another setting that can help with quality is printing speed. A moderate speed for printing should be between 40–60 mm/s. Faster print speeds can lead to imprecise prints which is very noticeable with small mechanical designs.

As a beginner you want to keep things simple for your first few projects Here are a few examples to consider:

• Spinner Designs
• Snake Chain and Scaled Projects
• Rolling Rings
• Clickie Mechanisms

Until your printer is properly adjusted don’t attempt designs that use magnetic systems or gear mechanisms.

The most common mistakes that beginners make include: failing to calibrate bed leveling incorrect heat settings and skipping calibration. Small setup details are very important and make a substantial difference. Once you’ve properly adjusted your printer you can look forward to smoother and stronger fidget designs and arguably most important better and more satisfying user experiences.

During a Monday deep work session the first fidget toy used was a classic spinner. It was a satisfying outlet for focus energy but quite quickly became a distraction. Constant movement was more entertainment than tool. It was in order of effect: low for noise medium for distraction and high for portability.

On Tuesday a clicking design was used. It was a great fidget tool but again the social work distractions of a phone call were noticeable with medium high noise and a low distraction level. It was highly portable.

By Wednesday the smaller 3D printed fidget toys had become quiet and easily handheld desk aids. The surprise winner of the week was a compact roller design. Movement could be sustained without noise or visual attention.

On Thursday an articulated chain-style toy was used during commuting and short breaks. It was flexible lightweight and easily carried. Repetitive movements however became unfulfilling. It scored in the order of effect: low for noise low for distraction and very high for portability.

The magnet form was tested on Friday. It was satisfying to use and brainstormed with during testing. However the magnets were loud when joined together disrupting the session.

After five days something became apparent: the best 3D-printed fidget toys aren’t the more advanced toys. For office workers and students a simple quiet and compact toy would be the most appropriate. A more advanced toy with a stronger feedback function would be more appropriate for workers with ADHD and those who are working remotely. Often the most simple fidget toy serving as a desk companion is the most effective.

The worry coin is one of the simplest designs and is great for a fidget toy. A worry coin contains a small surface with texture and even provides tactile feedback. Many designs of worry coins can be printed within a time span of 20 to 35 minutes take 5 to 10 grams of filament and cost around $0.30!

Another simple design is the thumb roller. The thumb roller provides great movement and is fully functional for even the quietest environments. The thumb roller can be printed in a time span of 30 to 45 minutes and takes about 8 to 12 grams of filament The cost typically is around $0.30 to $0.40!

If you want even more movement a small articulated fidget chain can help with that. Models of fidget chains use about 10 to 15 grams of filament and can be printed in a time span of 45 to 60 minutes. Many of these designs are print in place so beginners will not have to deal with assembly at all.

If you are looking for a fidget toy that is even more cost effective the mini gear spinner is a great option. The gear spinner is even a more mechanical fidget toy with a filament cost of about 12 to 18 grams and a printing time of about 50 to 70 minutes, The cost for this fidget toy is about $0.50 to $0.70!

For the best 3D printing experience use PLA filament It prints easily and works for projects needing fine details. Try an infill of only 15-20% to help cut down material use. Low filament fidget toys help prove that even fun projects don’t have to take a lot of material time or money.

Repetitive activity can include the tapping of a pen cracking knuckles or the clicking of a mouse Recommended Toy: Clicker Fidget.

Why It Works:

Clicker Fidget keeps idle hands busy and helps redirect the need for repetitive movement to a fidget toy that is purpose built for tactile feedback.

7. Managing Downtime Between Tasks

Short intervals of time during the work day can lead to wandering thoughts that draw the mind away from work.

Recommended Toy: Marble Maze Fidget.

Why It Works:

A Marble Maze Fidget is a great tool for short mental breaks that reset your concentration and focus but doesn’t draw your attention away from work for an extended time.

The best 3D printed fidget toys are designed to be not just fidgetable but also functional and practical for the everyday user. Rather than being distractions that take up space on your desk they are distractions with purpose.

One decent setting to try for fidget toys is approximately 0.2mm layer height. This is a decent balance of detail and speed and a reduction in the layer height setting for small gears can yield a smoother finish and edges when set at 0.12mm or less.

Fidget toys can also have spread limited to approximately 15-20% with many fidget toys falling around that range. More bending or repeated use will require a more dense structure (25-30% spread).

A common issue with articulated or print-in-place fidget toys is that they are designed to eliminate supports. Adding supports where unnecessary can cause parts with free DOF to adhere to each other and ruin the design. Always read the description to check for supports. When setting supports ensure that you use a minimum settings and preview the supports before printing.

Materials are important too. PLA is recommended as the best beginner material as it’s easy to use consistent and holds details nicely. If you’re working with fidget toys though it’s recommended to consider TPU as it has flexibility and prints great as a beginner material as well. PETG is a nice middle man as it’s flexible and durable however it’s a bit of a learning curve.

Some mistakes you’ll most likely run into are poor bed adhesion printing too fast and not considering tolerances. For moving parts scale down the design and use less printing and more cooling speeds. When designing fidget toys and considering every small adjustment will determine whether each individual piece can spin freely. Every adjustment is important for a successful fidget toy.
