The frame from the original design wasn't what i looked for so i just used the face-plate from the original and made a frame for my own.
The frame now has a compartment for a battery-box (max 52x90mm) which is accessible from the outside. I used a cheap one from “Action” for 99ct and soldered the switch out of it and placed it on the bottom of the frame
The author remixed this model.
Createt a new frame for the face-plate of the original design
