Here is a 3D printable version of the standard 0.8 40 teeth gear for the cforce mini motors as requested by @Spencer Nelson :)

I'm not sure it would be as strong as the plastic injection version, but it's worth the try. If it tests ok, i'll publish a wider version as well. PS : My advice on the print is to have the infill at a minimum of 70% et 90% to maximize the strength of those little inner teeth.
