I saw a fidget toy on youtube somewhere and thought that I could make that. I still had some old skate bearings somewhere so this must be an easy job. The next day people saw it and now I'm almost a fidget toy production plant. I have made three different designs: One with one bearing, one with three bearings and one with four bearings. I like the last one best.

The goal of a fidget toy is to fiddle with it. Just spin it silently instead of clicking a pen or flipping a lighter and irritating your surroundings. Some people even say that fiddling can help you concentrate.

Step 1: You Will Need

  • A 3D printer (with stuff like filament, software and a computer)
  • (old) Skate bearings (1, 3 or 4)

Well, that's all I guess.

Step 2: Print the One Bearing Spinner

Use the STL file to print the parts.

If you want to change something, you can use the 123D-Design file.

Print the parts with at least 80% fill. You need this for the weight.

One of the two knobs is printed inside the hole in the spinner.

Step 3: Put the Spinner Together

Push the (old) skate bearing in the hole in the spinner. You might want to use a new bearing, because the old bearings aren't replaced on your skates for nothing.

Push a knob on both sides of the bearing.

If the bearing won't go in the hole and/or the knobs won't go on, it might help to use a vise, hamer or shoe (or whatever)

Step 4: Start Fiddling

Hold the bearing knobs between two fingers and use a third finger to spin the fidget toy.

Step 5: The Three Bearing Spinner

Use this STL to print the three bearing spinner. Both knobs are printed in the bearing holes.

Push three bearings in the printed spinner and push the knobs on the middle bearing.

Through the extra weight of the two extra bearings, this spinner spins better than the one bearing spinner.

Step 6: The Four Bearing Spinner

Use this STL for the four bearing spinner.

Again the knobs are printed in the holes for the bearings.

This spinner works best, but is a little big to put in your pocket. Still I love this one the most.

I dont know how to make it still<br>
<p>That is so cool! If you don't mind me asking, what model is your 3D printer i am looking into getting one but i'm not sure on what to get?</p><p>Thnx, 7macs</p>
<p>Hi 7macs,</p><p>I have a Robo3D. I have their first (Kickstarter) model. I did some diy upgrades before it works like it does now. I would probably buy an other model if I would buy it now. Robo3D have a new model now that probably is much better. There are many YouTube videos that compare printers. If you buy a cheaper printer it probably takes more tinkering to get a nice print. </p><p>Good luck with it.</p>
Do you know how to make it without a 3D printer?
<p>use a hit glue gun and string gule the bearings together and rap the string around the glue to supportit then gule the string so it does not unravel </p>
<p>and you can take off the string after a couple of hours maby longer depends. if you do not use it for a day it has a better chance of not bearking</p>
<p>Try gluing bolts to either side of the bearing. These will act as weights.</p>
Hi Ezrak,<br><br>I would probably sculpt it and mold it out of resin. Or I could sculpt it out of wood. Or it would be really cool to cast it out of aluminum. You could probably even cut it out of cardboard. Or you could weld coins to a bearing. Perhaps it would even work with Lego's.<br><br>Probably some methodes would fail. That is the cool thing about making stuff, you are always learning and like Adam says: Failure is always an option!<br><br>Have fun with it.
Hey, this might be a really stupid question but is there any chance that you might be able to make me one and send it over? I have absolutely no materials to make one and I have tried to order one but it didn't arrive! I have a huge fidgeting problem and I need something like this to help me! Its okay if you cant, I just thought it was worth a shot. Sorry for bothering you.
Hi Alison,<br>That depends greatly on where you live. If it is somewhere in the west of Europe, than I'm sure we can arrange something.<br>If it is somewhere else in the world, than you might want to try aliexpress or eBay.<br>
<p>How Big Do You Have To Put It For It To Fit The Bearings?</p>
<p>I Tried To Print One And The Bearing Didn't Fit</p>
<p>Hello Gabrielacosta</p><p>If you print the spinner at 100%, a standard skate bearing should just fit. Sometimes it helps to use a rubber hammer to get them in.</p>
<p>What is the name of the material you used? I have a 3D printer i just lack the raw material.</p>
I use PLA, but if your printer can handle it, you could also use ABS or PETG or something.
Here's my attempt out of wood. It certainly isn't balanced perfectly and it's a little big for my hand but it's pretty and still is fun to use!
<p>Sorry for a late reply, but I am looking to make one, and would like to know if yours is heavy enough to keep some momentum for longer spinning. </p>
Or like we say it here: &quot;goe gedaan jochie&quot; ;)
Wow, a really great result!
<p>Those inlines (rollerblades) bearings are usually pretty worn, I have bought kiddie skateboards at Toys-r-us for very little money and gotten brand new bearings. I built my cnc robot out of these :) </p><p>Can someone convert the 123dx files into DXF? I can't open them and the stl files are difficult for me to mod into 2d for cutting. I have a stack of acrylic sheets waiting to be made into these. </p>
Hi stringstretcher,<br><br>If you open the 123d file in 123d-design, than you can mod them any way you like and export them in any format you like. The 123d-design software is free for mac or windows.<br><br>I hope this helps.<br><br>Peter
<p>how do i get it in an stl file</p>
<p>Or on step 5 or 6 if you want to print that model.</p>
<p>Go to step 2 and you will find the file there.</p>
Would you mind if I sold these at my school? I made one already and people are very interested. Please let me know because I'm not sure if you have a patent or copyright. Please let me know, thank you!
<p>No problem if you sell them on your school.</p>
<p>there great if you have adhd</p>

<p>A buddy of mine works with autistic kids and said these would be perfect for them, we are making a bunch.</p><p>I am also going to try to make versions that light up when they spin, and are smaller for the younger kids hands (they enjoy the 2 and 3 pronged ones, and i think i can keep the prongs, remove the bearings, make them a little shorter, and fill the ends with bbs for weight) </p>
I'm really curious for the lighted version. Please post it if you managed it.<br>I did some ties to make a smaller version, but until now I didn't manage to make something good.
<p>I made this and it's very cool! One problem though, the handle pieces don't fit. They don't stay together because the hole is too big. Am I supposed to use a bearing spacer to make the hole smaller?</p>
Hi,<br>If you use standard skate bearings with a 8 mm hole, the handle piece is supposed to fit snugly. Without using spacers. The settings of your printer might be the cause here. Perhaps a little drop of glue might do the trick?
you could change out the outer bearings with Penny's , nickles, or dimes <br>It would be cheaper than three more bearings and it would only take a small adjustment in the design
I tried that with our European cents and it does work, but I like the design with bearings much better.
<p>Spectacular design! This came out perfectly and the bearings fit like magic. One question, the file printed with only 2 of the caps. Can you share a file for just the cap pieces? Thanks for sharing, your design of this piece is top notch!</p>
<p>Nice to hear.</p><p>Here is the file for the button: http://www.123dapp.com/123D_Design/fidget-button/6345020</p>
How does one make one without a 3D printer?
<p>As you can see, JdeZwaan did one in wood. But you could also go to a makerspace or fablab, where they have 3d-printers and they can help you with it. Or you can order a print at a 3dprinters hub or 3d printing company like shapeways. </p>
<p>I made two of these for me and my buddy and it works great. The blue prints fit the bearings i bought perfectly. All we had to do was use a rubber ended hammer to knock the bearings into place. I also used red brand bearings.</p>
<p>Great to hear. I now made some in blue with bearings with a red dust cover. And that looks very nice. (not red brand, but also with a red dust cover. Red brand is not for sale here)</p>
<p>That sir is brilliant!! My boys and I are constant fiddlers so I can see making these for us. I've got bearings from a scooter and some beautiful maple burl I can use for the main body. Thanks for the great idea.</p><p> Cheers.</p>
<p>please show the result :)</p>
<p>I would recommend Bones Red bearings as they have good bearings and to remove the bearing guard because it hinders the performance and the bearings are going to be covered with the knobs.</p>
<p>I now ordered the cheapest bearings I can get for the outer bearings and more expensive ones for the centre one. I will let you know when they arrive and if I can feel the difference.</p>
<p>Im not familiar with skateboard bearings, do they come in different sizes and if so what size do these STL designs require once printed?</p>
208zz bearings, standard skateboard bearings.
Hi TK,<br><br>Skate bearings are 22 mm outside, 8 mm inside and 7 mm high.
