9-18V Motor (RadioShack) Gearbox

thingiverse

This is a Gearbox Housing for a 9-18V Motor I got at Radio Shack (http://www.radioshack.com/radioshack-super-speed-9-18vdc-hobby-motor/2730256.html). The Internal Gears and Hardware are from a Tamiya Gearbox (https://www.pololu.com/product/114). I just wanted to adapt the gearbox so I could use a bigger motor. I printed this with 3mm layer height on black hatchbox abs filament with the motor lock tab down on the print bed. Update: I had to use a 3mm drill bit to smooth out the holes and a Dremel tool to smooth our where the motor mounts. I may need to update those sizes for the holes but that worked just fine for me.
