Another slew bearing

Pulled from: https://grabcad.com/library/bb-rt-01-100-es-slewing-ring-bearing

The original design was scaled to fit two sizes of balls and mounting holes:
All 5x scaled parts - balls and holes 3 mm;
All 10x scaled parts - balls and holes 6 mm.

It has 60 balls that can be printed or bought separately.

This is intended for use in a robot arm, and a driving gear is available:
