Personalizable Ball Fidget Spinner

This is a pretty straightforward fidget spinner with two distinctions. It takes 5/8" loose ball bearings on the arms, which fit precisely so they also rotate freely. Uses a standard skate bearing (608) in the center like others. Both the spinner caps and arms can be embossed with a 100x100 PNG image. You will need to print 2 caps. Otherwise pretty basic spinner. OpenSCAD files provided.

The bearing in the center should fit pretty tightly. The loose bearings on the arms should snap in from the top side and then rotate freely. If the dimensions don't come out perfectly on your printer, the OpenSCAD files have "tweak" variables you can use to get a secure fit.
