This design includes 4 parts:
- Bluetooth controller holder (clip.stl)
- Rail holder (Hold to clip.stl)
- Button (Button 1 and 2)
I extracted the Bluetooth controller and Button 1 from another design: https://n9.cl/nht68 or ...thing:7004808/files by: juanlopezavo
I designed the other parts by myself.
I used PLA with 2 walls and 15% infill, and other standard parameters.
Assembly is simple and intuitive (see photos). I used double-sided tape, but I also included holes to hold the parts together with two small screws.
However, to make the device work, I had to experiment. Tutorial in YouTube: https://youtu.be/9HiIshVap-A?si=YkqFo2ApRmw4rq-n
