Brushless Planetary Gearbox

This is a simple yet effective 3D printable planetary gear for 5208 brushless motors.
Gear ratio is 4:1, quialifying the resulting actuator as a semi-direct drive.
I personally use DYS gimbal motors and need more torque than they can provide, while maintaining them at an acceptable current draw.

Works great with any 5208 motor, as long as they provide the right mounting holes configuration.
