Single Torus Bearing
thingiverse
Because of the slippery nature of PLA, printing it with no moving parts between the outer and inner rings tends to work better. This design should be printed without any supports. You might need to experiment a bit to separate the middle ring from the inner ring, as they can sometimes stick together.
