The case needs 4 screws 3x12mm and 4 screws 3x20mm to be assembled. The button caps need special rings that are attached to their bottoms in order to hold them in the upper part of the case. The frames are installed into the case without any glue for easy disassembly. See the pictures for more info.

I recommend to glue 4 small rubber feet onto the bottom of the case so that it doesn't slide on a flat surface. But avoid covering the screw holes.

The images for engraving are attached as well as the photo of the end result. The logo is not the official logo of the Trolsoft, but my own design.

If you own a 3D printer, you are allowed to print and sell the cases for this device. But you are not allowed to sell the STL files.
