Thrust Bearing

Sized for 9mm balls and 2-4 mm screws
I printed this out of PLA for use in a turret central axle bearing and used 9mm steel slingshot ammo as the bearing balls. Print settings were 0.20mm layer height, triangular 60% infill, 3 wall loops and 6 top shell layers(Creality Print 6.3 slicer).
Could support at least 150 lbs. without sticking or cracking.
PLA will soften from friction-induced heat if used at high speeds(probably don't use this at high speeds).
