Update 22.4.2017
I added new shaft component. If you have trouble to print original shaft try "gearbox_shaft_v2"

Few hardware parts needed to make this work. You will need also 2mm drill bit. Check link to see how to assembly it.

Would you happen to have the .step file available anywhere for modification? I would be personally interested in modifying the motor mount especially.


I only have a original google sketch up file. You can find it here.

Alright, I'll try to make what I can with it. Thanks for what input you could give regardless!

By the way, if anyone doesn't have a brass rod, a wire clothes hanger works alright as well.

can you link the file of one gear? one gear failed dont want to print the hole set again :) its the medium one ;)
thanks a lot!


You can delete unwanted gears from the STL file. Just open it with your slicer and "ungroup" the gears. (At least Slic3r have that feature.)

Motor looks almost same but I cant be 100% sure if this motor will fit. There's no measurements for the motor fixing positions.

This one will fit. Fixing screw hole distance: 16 MM

Wonderful design! What CAD did you used?

I'm using google sketch up (make version) :).
