How to print

Three parts: the body plus two caps. Print them on one plate or one by one, flat, no supports, no bearings.
0.2 mm layers, 100% infill for a heavier, longer spin.
Push the pin cap up through the body, then press the socket cap on until it clicks.
Too stiff to spin? Raise the clearance a little and reprint.
