Super Bearing Cap - 22 mm

A classic fidget spinner bearing cap. The concave surface prevents slipping out of your hand. It's the full 22 mm diameter of a skate bearing, offset just enough from the surface that it won't rub the bearing or the spinner.

Remove auto-generated support from the hole in the top piece, or you will have to dig that out with a pick. Your printer can bridge it and it's hidden.

You may need to scrape a little excess plastic for a snug fit. Glue is optional.
