Print-in-place caster wheel

Print-in-place caster wheel that I designed as an experiment. Works better than you'd expect although it needs some breaking-in time to smooth out the internal plastic ball bearings.

The swivel shaft is printed separately and clicked into place. Shaft diameter is designed to be a snug press-fit into a 9mm receptacle.

Wheel diameter is approximately 43mm. Wheel rolls freely on 12 internal ball bearings that print in place.

It is shockingly strong and can easily tolerate a working load
