Small Test Thrust Bearing

This is a small thrust race to take 14off standard 6mm BB pellets. It doesn't clip together or have any fancy captive mechanism as I just wanted something quick and simple to get a feel of how well BBs on ABS might work. I will test a Nylon filament before going ahead with any actual design but I was very pleased with the results, considering there was no appreciable lateral slop and I could stand on it (~83kg) and spin around quite happily. Probably wouldn't last forever though...

Obviously you'd need to print two.

Approximate dimensions:
