Fidget spinners are all the rage! I noticed however, that all of the existing fidget spinners are designed only for very specific sizes of bearings, so I decided to create one with customizability in mind. Use the customizer to put in specifications for the bearings you want to use, the number of legs of the spinner, and how long the legs are!

To create your very own fidget spinner, simply click on the Open in Customizer button above, adjust the parameters to fit the bearings you have at hand, as well as a handful of other bits, then generate your STL, print, and post pictures! I'd love to see other people's fidget spinners using a variety of bearing sizes! All of the parameter measurements are in millimeters.

Look for updates in the near future that will include better cutout/finger groove generation, compatibility with different height bearings, and maybe some grip or ninja star-like points for added aesthetics! Feel free to comment for other suggestions or compatibilities that you desire.

Update 2016-11-12 - Added a couple of manual adjustments to the 'cutouts',.. I've been trying to find a good way to automatically generate a nice little cutout between the bearings, but I don't think there's an easy universal way of doing it. I need to delve into using a curve rather than just using cylinders.

This is a great design! Printed it and it works really well. I like the edges...gives it a little grip.

Thanks! It was happenstance that I ended up with those edges, but I rather like it as well. Good for single hand spinning!

Hi , I have 6001 bearing D 28 d 12 B8 but the program doesnt make it right :-/ also I think there is mistake in line 96 . when im using all the same bearing there should be outside radius --- > r=oRadius , or am I doing something wrong ?

If you're using the same bearings inside and out, oRadius should be equal to iRadius, so it shouldn't matter. On line 96 it is cutting out the holes for the outside bearings.

As far as your 6001 bearing not working, what's not right about it? I'd need a few more specifics to help with that. If the hole is too small, you may want to increase the horizontal play to slightly increase the radius. It will depend on the printer on how much the play needs to be.

It modeled as separate pieces. not one thing. so it could not be used. try it yourself . I posted the simensions of the bearing. I used 3 bearings on out , one in the middle.

So putting 14mm for the inner and outer radius works just fine with the rest of the settings default. Putting 28mm for the radius (which would be a 56mm diameter) causes some issues, in which you need to increase the length of the legs to space the bearings out. You may want to try tweaking some of the other settings such as the curve settings.

Great! Configuration, printing and finally the spinner worked like a charm. Thanks a lot for sharing!

Thanks for trying it out and printing!
