Experimental Chassis For GoPiGo version 1.0 (untested)

**Updated design 10/19 to allow greater clearance for back of motors and to clean up design.**
This is an untested design for a replacement chassis for the GoPiGo robot (https://www.kickstarter.com/projects/john-cole/gopigo-the-delightful-raspberry-pi-robot).
The dimensions are too large for most hobbyist 3d printers, so my next order of business will be chopping the design into two pieces which can be bolted together. I will also be receiving a large format 3d printer at the end of the year (https://www.kickstarter.com/projects/cobblebot/cobblebot-3d-printer), at which time I may revisit the large scale design in version 1.0.
This design is made freely available and improvement through modification is encouraged. If you choose to upload an improved version, please rename the version number appropriately (you can jump to 1.1 or 2.0, it makes no difference to me) so that other users can tell them apart easily.
I hope this makes someone's life a little easier, and I apologize i
