Motorholder / Motor mount and Pinions for SG1603 SG1604 RC Car

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.
