This is a case designed to mount on the back of my printer. It houses a Ramps_1.4 control board/arduino Mega 2560 and a Raspberry Pi. I run an Octopi Server via the Pi which is absolutely awesome by the way so you guys should definitely give it a try.
There is a hole on the back for a DB 50 connector which I use to hot swap control boxes (ramps, smoothie, duet....) easily between my 3d printers.
I printed these from PLA with a 0.5mm nozzle, 0.35 layer height without support.
I did have to file down the hinges a bit on the lid to fit the base, but the result was a snug fit.
This is a work in progress, First revision
