Arduino Mega Enclosure with Shield and Brackets

These are files used to print an a mountable enclosure for an Arduino Mega that has a shield mounted and a battery case. The mount on a square shaft. These may be valuable to someone as a starting point for an Arduino Mega project. I haven't put much work into this to clean it up, the SCAD file is quick and dirty modification of a battery case file from
Heinz Spiess, found here at Thingiverse, though I ended up using almost none of that.
