This is the best 3D Printed public domain bearing to ever exist. It includes tight clearances for modern printers. It spins great, but even better with WD-40. It can be used in place of an actual bearing, or even a fidget! If you thought it would take forever to print, it takes less than 30 MIN to print! 41 OD, 18 ID. Push pins on both sides of bearing to loosen it.

This is one of my first public domain project!
Although it is public domain it would be great if you can give me some informal credit if you use it in a model!
