thingiverse
This is a heavy Lazy Susan style bearing. Bearing race is sized for 18, 1cm diameter ball bearings, plastic or metal. The top and bottom half interlock with raised and sunk raceways to prevent side shifting and 12 simple clips reach from pockets in the top half, to raceways in the lower half to keep the clam shell together. After assembly, the clips are held in place with small self threading screws, sunk from holes in the top. The top and bottom clam shells have almost 1cm of meat to screw into for mounting on your projects. Screws should be places to either side of the ball bearing race. Hardware needed: 12 small screws with a 2mm shank. edit1: had to reupload the top and bottom shell. didnt work the first time.
