625 Bearings

thingiverse

Must print with raft or you will spend forever trying to clean the ball bearings. If you don't use raft, the bearings will be impossible to print. I printed a storage unit stand for the PSU and the drawers required 8x 625 bearings. Since this is not a build that requires heavy use of the bearings, I decided to try making one in fusion 360. It's basicallly a 16mm round, 5mm wide with a 5mm hole in the middle. This was used in the print I made from : https://www.thingiverse.com/thing:2612534 Depending on your printer and material, may still need to file the hole in middle to ensure you have 5mm there. Once you do that, pushing in the middle should cause the tiny adhesion to the ball bearings to pop and the bearing now moves. Note, don't even try this for fast regular movements that require a real bearing, but it should be useful for things like drawers.
