Designed to be used with Adafruit's LCD shield kit with buttons (one example: http://www.adafruit.com/products/772) and Carlon electrical box (P/N E989NNJ). I purchased my Carlon 4" x 4" x 2" box from Home Depot for about $7.00. The box does not have any holes in it (for sensor wires or power), so you'll have to add those yourself or make another box. To activate the reset button you will need to use a paperclip or similar small pin.
One STL has text on the buttons and the other does not.
If you want to make your own box, the overall height x width is 101 mm x 101 mm and the holes are 3.625 in x 3.625 in center-to-center.
Sliced @ 0.2mm
(4) M3 x 10 mm screws
(4) M3 nuts (optional, I just threaded into board because PCB diameter was small)
(1) Carlon box (or equivalent)
