small ball bearing

thingiverse

I made this small fully printable ball bearing with a classic 3D printer. There is no need for supports because I have already integrated them. The outer diameter of the ball bearing is 20mm, the inner diameter is 6mm and the height is also 6mm. Once the bearing is printed, all you have to do is cut the small rods that held the balls on the printing plate. After that, the ball bearing is fully functional!
