The box of the prototype consists of 4 pieces designed with Freecad to be 3D printed.
I used PLA, heating the bed up to 60ºC and the nozzle to 200ºC.
Mounting is very simple and though the design includes eight blocks at the corners to allow screwing I found it wasn’t necessary as the pieces stay together after mounting due to pressure.
The four ‘columns’ at the base allow mounting a PCB over them and some wires can pass down it.
