at work I needed to mount a mini stream deck on a rack panel, flush. Not finding anything I drew one, there are many guides on how to disassemble a mini stream deck, the most difficult job is to desolder and re-solder the USB cable, nothing that even a novice maker isn't able to do. The display-button block comes out as a single body from the original case and just insert it into the printed piece, once inserted, re-solder the USB cable, apply some hot glue to prevent the cables from breaking where they are soldered to the PCB and mount the rear piece which also acts as a cable guide, for a rear and stable exit, fix with two m3x15 screws. The hole to be created in the panel where the new piece will be fixed is 85mm*70mm. Finally, everything is fixed with 4 M3 screws in the 4 corners.

I do not take responsibility for any damage caused to your streamdeck during disassembly and reassembly operations, and the warranty could become void, so be careful.
