An idea for a 44:1 robot actuator I'm cooking up. Split-ring compound planetary gear system which uses bearings instead of gear teeth to eliminate the source of the huge inefficiency typical of these gearboxes.

Should be able to print the ring gears in assembled positions. At 0.2mm layer height, a one-layer gap should separate them and be easily de-laminated post printing.

HK0306 Bearings and M3 steel dowel pins of 12mm, 18mm and 42mm lengths, some screws and a NEMA 17 stepper motor or two.
