This thing is my original design of a 3D printable case for a flame controlled MIDI controller
Here is it in action:
Project instructions can be found at : http://www.instructables.com/id/Flame-Controlled-MIDI-Controller/
The case is designed to be versatile for many printers (hence the minimal use of overhang), and for many electrical components. Therefore, I have left out screw holes on the front panel, as well as the rear. I have also omitted holes for the USB, switch, and IR LED because not everyone will build this device with the same components as me. But, its not too hard to just drill out the wholes as needed! I suggest printing out a small bracket with two screw holes to secure the rear of the case. Thanks for your interest!
