Chassis for Arduino-Controlled Servo Robot

Here's the STL files for my recent 3D printed drive-train. I created the pieces in Autodesk Inventor. I also created a mount-adapter for an Arduino mount found here: http://www.thingiverse.com/thing:101985. I only had square nuts, which explains the square holes. I can make a modification for you if you need it, just request it in the comments.
