This is a group of modifications on http://www.thingiverse.com/thing:19170 by Krux. I stretched the chassis to tighten up the tracks and combined the 3 parts into one. I found that the original idler wheels were too loose on a standard 608 bearing so I reduced the diameter of the hole.
I extended the servo mounts up to meet the new top plate, and created the top plate to take a servo for future turret/head/upper body. The front plate mounts into a recessed area in the top plate which can be glued and screwed tight using the nano and uno plate mounting holes. As I used ABS, acetone glued it very well.
The Arduino nano screw terminal breakout board I used is a Deek-Robot nano terminal adapter v1.0 from e-bay.
An Arduino Uno bumper plate is also supplied to mount onto the front plate. All holes already in front plate.
