Gear Bearing Spinner - Customisable, parametric

Included STLs are for 4mm allen centre hole and M8 nuts (or no nuts). Height is 8 mm and tolerance is at 0.15. Adjust accordingly for your printer tolerances and preferences. The nuts are not necessary but more mass means more spinning. If you decide not to use nuts, you may want to print it with more infil.

Open 'bearing-spinner.scad' to make changes. The SCAD file can take a while to render.
