Ok, so below you have the .STL files for the 3D case. Dwonlaod each file and print them. They are already oriented so you don't have to do enything. The case is made out of 4 parts. The top aprt, the bottom part and two small push buttons. I've used PLA material for each. Alos, a 0.4mm nozzle of my printer, 0.2mm layer height, 2 perimeters and 100% infill at a temperature of 200ºC.
