Can be used for wheels, robotic arm parts, pivoting attachments for an XRP robot, etc.

10:1 gear reduction 

If used in a robot, make sure to lubricate gearbox with lithium grease or equivalent. 

Tolerances are 0.25mm - If mechanism binds, check print for issues such as elephants foot and re-print part.

Please print parts, especially “Eccentric Shaft” with the strongest material available, otherwise it is prone to breaking under high forces. PLA should only be used for this if this print is used as a demonstration piece with no load. If PLA or PETG is the only option, print small pins at a slower speed and higher temperature. Use heated chamber if possible. (anything to have stronger layers)

The gearbox should be separated from the motor by a gap to prevent any warping from operational heat.

Print “Outer Shell” from transparent resin for internal mechanism to be visible.

0.2mm nozzle recommended 

STEP files are linked for modification and use for robotics. Open “Output Drive Blank” and modify for any output shaft 

Print:
