BB thrust Bearing
thingiverse
Simple 35 mm thrust bearing, using airsoft BBs. To make one, you'll need some airsoft BB balls and a single 3 mm screw. You have to print two parts of the body and one axis, then put them together - see pictures for more details. I've used it for painting tables or anything that puts pressure on top and needs to spin freely. This bearing was made with Tinkercad.
