3D model description

This is not a normal Planetary GearBox, but a Compound Planetary GearBox which gives more ratio in a small space without stacking gears.

ideal for cranes and other applications with extreme torque, no backlash, extreme precision, less load effect on electric motor, compact and compatible with LEG technic.

Ratio: 51:1
Size: d = 39mm - h = 24mm

3D printing settings

Nozzle: 0.2mm is better, but 0.4mm is fine
Layer Height: 0.2mm

A calibrated and precise 3D printer is needed, if the gearbox is too tight it is necessary to make adjustments to the horizontal expansion, the assembly needs to be with correct gaps because as it does not have any hardware it is necessary that everything fits correctly
