SMARS modular robot chassis remix

Remix of the chassis for [tristomietitoredeituit](https://www.thingiverse.com/tristomietitoredeituit)'s awesome SMARS modular robot (https://www.thingiverse.com/thing:2662828).

Redesigned from scratch in openSCAD to permit addition of 2xAA battery holder in the base. Axles designed to suit Pro tracks (https://www.thingiverse.com/thing:3807011). Includes an insert to hold the N20 motors in place and provide a guide for the motor wires.

Chassis is slightly wider than the original to fit the longer AA batteries. Consequently the guide rails for the Arduino Uno have been redesigned as well.

OpenSCAD files included to permit customization if you wish.The AA battery holder (openSCAD file included) is just a copy of my AA battery holder design: https://www.thingiverse.com/thing:3884172
