Differential used in the OpenRC Truggy R/C car.
This is the OpenRC 1:10 RC Differential.
The genereal idea was to create sort of a template this t...ime.
As you can see, i have attached three different STEP files, one is the front and rear diffs used in the OpenRC Truggy: http://www.thingiverse.com/thing:42198 and one is the central diff for that same car. The third one is a "clean" case and the idea is to provide something you can modd and add your own type of gears to.
Here´s a video on how to assemble this diff:
