Summary

Inspired by some other designs here (special thanks to Chillance for thing #24660), I tried to make a enclosure for my reprapworld keypad. The basic idea was to have symbolic keys (in the future I will print them in different colors).

At the moment I have printed the first prototype (see pictures). Next step is a lid for the box with mounting-possibilites to the different rods (6 and 8 mm). As soon as I have finished the whole thing, I will release the openSCAD-source file here. Hopefully the openSCAD-file will be with some parameters to fit the design to your needs (wall thickness, button thickness, ...).
The final version will also have a smaller knob (the one in the pictures looks definitely too big).
