Some years ago there was an article in Hackspace magazin from Dr Andrew Lewis about a touchscreen for controlling a K40 Laser fitted in a tin-box. I liked the idea, but didn't have access to a suitable tin-box. So I cut a front panel with the laser cutter and printed 3 parts to screw through the plexi into the touchscreen an hold together the cables.
In the bottom 2 magnets 20x3 mm hold the piece on the housing of the laser cutter.
The author marked this model as their own original creation.
