Adafruit Feather Rover chasis and top

This is my version of a chasis and top to resemble Adafruit's aluminum chasis and top plate for their rover used in the Feather Rover and RPi Rover. I intentionally bought everything but these pieces to force myself to create my own. Even though they sorta resemble Adafruit's in spirit, everything is from my own measurements. It's still a work in progress, the 4xAA battery pack didn't quite fit like I wanted it to on the top (it's not an adafruit pack) so I resorted to tie-wrapping it until I can revise the model a little. But other than that, every thing lined up for the Feather build per their instructions (motor board and feather on the doubler) and fun has been had. It's a fun little project when complete and works as expected.

For spacers I used m3 40mm, customized version of thing http://www.thingiverse.com/thing:710249
