A simple wrist mounted fidget spinner.

It takes a standard skate bearing and 5/16" hex nuts.

The band is capable of holding a 1" by ~2mm thick fabric elastic band sewn shut or hook and loop fasteners sewn onto the ends or just a 1" hook and loop band if you don't mind the scratchiness.

Have fun, I have everything in one print and it should be capable of printing without supports but the individual parts are still included if you need a replacement part or you want to remix.

This should work with any fidget if you or your kid wants a different fidget on their wrist.
