Arduino Mega Box
thingiverse
A box for the Arduino Mega with spacers that fit into the holes on the circuitboard (at least, they work for mine). The lid is two pieces with a large hole in the center for any wires coming out of the box. This way, you don't have to string any wires through the lid and can add/remove/maintain without any trouble. The side that has spaces for the USB and power has a grid of tiny holes for ventilation (intake), and the opposite side has a hole to be covered by a cooling fan. The lid is a pretty tight fit once you snap it on fully, so be careful when you take it off.
