3D model description

I made a 3D model for the original motor mount of the SG1603 because I couldn´t remove the pinion from the orignal motor. I also made my own version with a 14T Pinion for higher torque. The gears need to be printed in Polycarbonate, I would also recommend to print the motor holder in PC, or any other high temperatur filament, since the brushed motor gets quit hot.

I also would recommend to print the gears without the screw holes and simply heat the tip of the motor shaft and let the gear melt onto the shaft.

3D printing settings

-0.15mm layer high
-0.4mm Nozzle or smaller
-4 parimeters and 100% infill
-print the gear slowly

For Polymaker PC max on a Prusa Mini+ i recommend 250C nozzle and 90C print bed temperature.
