Design Support time lapse/timelapse remote mod by Bluetooth

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: juanlopezavoI 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.
