My MPCNC control pendant with full credit to Slavulj for idea of using membrane keyboard and Arduino, and for the basis of the code, and to OT12345 for the design of the case.
It uses an Arduino Nano wired to RAMPS via Gnd, 5V and TX (TX from Nano to RX on RAMPS), lines as per INO to keypad, ditto via 220ohm resistors to LEDs for axis indication.
I redesigned the front panel to suit my LEDs (4mm flat top) but just drilled the mid section. I've now designed that in OpenSCAD too and ditto back with Nano slot and USB hole.
Update:
2018-04-04 - NewMid.stl now has slightly larger LED holes - tweak SCAD LEDHoles module if still not right for your LEDs. There are three diameters in there to play with!
2018-04-04 - NewBack created. All Nanos are slightly different sizes so it might be a tight fit or might need some hot melt. The USB cover may need a file to fit correctly.

I only called my CNC machine a printer twice, which is pretty good for me!
Note the code is set for 115200 baud and you'll need to check this matches your CNC firmware.
