Edit 2013-04-26: Corrected version of Central Diff plate Rev A.3) uploaded.This is a redesigned version of OpenRC 1:10 RC Differential.New internal gears and lots more minor improvements.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.HereÃ�Â´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/112745535856143176146Home - Things - GooglePlus - Twitter - Facebook - Youtube - Instagram - Vimeo - LinkedIn

Inspired by Thing-O-Fun's "Functional Differential Gear System" I decided i should make one for my RC car. So i did.I scaled down the gears from the above mentioned Thing, and designed the rest of the parts in my favourite cad software.And it works surprisingly well, my car is 4WD so i have two of these in the car right now!
A simple tool to aid when putting together the OpenRC Differential.You can download the OpenRC Differential here: http://www.thingiverse.com/thing:79938Assembly video (not using this tool): http://www.youtube.com/watch?v=Th_myFCZTWo
Remixed Differential from Thing-O-Fun. I added the Yoke to make it more realistic. The original files had a lot of play and were not all consistent sizes which are now consistent. I also redesigned the spider gears to accept screws from the outside to allow 4 spider gears to be installed.Addition:I added a stand with a motor from here http://www.jameco.com/webapp/wcs/stores/servlet/Product_10001_10001_2128219_-1 . Use the 2 spur gears to drive the entire assembly. Motor can be wired to a USB port.Functional Differential Gear System  by qsopc  is licensed under the Creative Commons - Attribution - Share Alike  license. http://www.jameco.com/webapp/wcs/stores/servlet/Product_10001_10001_2128219_-1 https://www.thingiverse.com/thing:737465 http://www.thingiverse.com/qsopc http://creativecommons.org/licenses/by-sa/3.0/
