Super Bearing Cap - 21 mm
thingiverse
<p>A classic fidget spinner bearing cap. The concave surface prevents slipping out of your hand. It's slightly smaller than the diameter of a skate bearing so the bearing just shows through the gap.</p> <p>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.</p> <p>You may need to scrape a little excess plastic for a snug fit. Glue is optional.</p>
