Mini Fidget Spinner

thingiverse

Problem: I wanted to print a fidget spinner, but only have 10x5x4mm bearings. Solution: Make a mini-spinner to fit those bearings! It's a bit smaller than the normal spinners, and a lot lighter. I assume it's not the best for doing tricks or anything, but it works as a plain old spinner. These bearings are common in RC cars, so I had a ton of them to use. I recommend removing the shields from the bearing and using a solvent to remove the grease from the center bearing, so it spins more freely. Only required parts are the bearings, and a drop of superglue to hold the halves of the hub together. EDIT: Added plugs to replace bearings on the outside, if you don't want to waste so many bearings.
