Simple emergency stop button panel. I designed it for the 3dpBurner2 3D printed laser cutter/engraver ( http://www.3dpburner.blogspot.com ), but it can be used for any other project. I use it on some 3dpBurner2 machines instead the full control panel.
Print on STL position without supports.
It´s ready to be fixed by using M3 stuff, double side tape or hot glue (i use double side foamy tape).
See pictures for assembling (the machine picture is of a previous version).
