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.

<p>omg this is awsome </p>
<p>where do u get 3D printers</p>
<p>I bought mine on kickstarter from Robo3D.</p>
<p>u think this is cool i do 2</p>
<p>Hi. How long did it take to 3D print the fidget Spinner </p>
that depends on the printer used and the settings. For me it takes between 1 and 2 hours.
<p>can you make me one because there are all of these kids and i don't have one</p>
If you live in the Netherlands, than we must be able to arrange something. If you live somewhere else than I probably won't be able to help you.
<p>Thanks for the post! Had to make holes for the bearings a wee bit larger. Will try the WD40 trick next.</p>
Made a couple of designs. I would suggest to remove the grease on the ball bearings to make it spin faster.
<p>Nice! Which design feels the best in your hand? (I think it is mine, but I didn't try any other designs :) )</p><p>And yes, running the bearings on WD40 instead of grease is much better for a spinner.</p>
<p>Hi just to let you know, soak the bearings in petrol and they will spin like hell! Then apply wd 40 and it will come out great! please look up tooth pick shooter and subscribe. i am thinking of making a awesome rubber band gun as well that shoots further than you will get from a hand rubber band gun. awesome project 5 stars !!!!!</p>
Its a matter of preference, I'm trying all the designs I can print, your design is great. Simple and easy to spin, just right for my hand.
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>What size bearings do you use</p>
<p>use a 22 mm bearing off a skateboard thats what i use when i print them</p>
I live in the united states
<p>Perhaps someone there can help you? You might have a local maker space or fablab?</p>
<p>i don't know but if you don't have any bearing like me do this one.https://www.instructables.com/id/How-to-Make-Fidget-Spinner/ </p>
<p>nice!</p>
<p>is there a easier way and safer way to make one if yes then tell me</p>
<p>What do you mean with safer? </p>
<p>can someone make me one and I will tell you more info if you say yes?.</p>
<p>If you live in Western Europe, I can.</p>
<p>can I use rollerbalde bearings to make a fidget spinner?</p>
Absolutely, that is what I used.
what kind of rollerblade bearings should I use?
<p>Use the cheapest that spin nice.</p>
<p>I don't know if anyone else had this problem, but I had a hard time getting the bearings in. When I finally got the last one in place the center snapped. I have my printer dialed and my tolerances are low, so I think the bearing holes are a little on the small side. Perhaps it's the difference between pla and abs (I use abs) as pla is a little bit more flexible. Going to make the holes a tiny bit wider and see what happens. Otherwise, been playing with the broken three bearing fidget and I absolutely love it.</p>
How much does a 3d printer cost?
That could be anywhere from 200,- until 3000,- or even more for pro-printers.<br>For around 500,- you can get a nice kit already.
<p>Look into a P3Steel. They're great, reliable rep-raps.</p>
<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>me to</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>
I dont know how to make it still<br>
You can try any skate-shop. Online depends on the country where you live.
AMAZING YOUR A REALLY GOOD FIDGET SPINNER MAKER
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.
Thanks
<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.
