Summary

Remix of the original by Lakaii. This housing, end cap, coupler, and thumbscrew allow for the use of an upgraded hi-torque/low rpm gear motor. Print will need minor hand finishing for proper fit. I chased all small threads with a tap, and filed/sanded as needed for a perfect fit. You will need to drill and tap the gear motor shaft (M3) in the approximate location of the original. two additional M3x4 screws and an M3x25/30ish will be needed as well. Motor is reverse rotation from the original, solder the black to + and red to - for proper rotation. Back spin the end cap a few revolutions before assembly to allow for the cable twisting while tightening. Works great on My G2 SK5000. The gear motor can be found on Amazon. I'm still bad with links and such. It's a "Greartisan DC 12V 5RPM Gear Motor High Torque Electric Micro Speed Reduction Geared Motor Eccentric Output Shaft 37mm Diameter Gearbox"
