This is the OpenRC 1:10 RC Differential. The genereal idea was to create sort of a template this time.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: http://youtu.be/Th_myFCZTWoIf you have any questions or any other thoughts you want to share please visit the OpenRC Google + community here:https://plus.google.com/u/0/communities/112745535856143176146
