Quick-release safety tether (GoPro, DJI action, Ezviz, action cam)

I wanted a secure my DJI Action 2 and GoPro to my helmet in case it falls off for whatever reason you can think of. 

Printing;
This little 3D print consists of 2 parts; the main receiver and the carrier. You can load them into prusaslicer, split them into objects and print them separately without support. 

Assembly;
Tie the carrier to a string, which attaches somewhere to the camera. 
The receiver end needs to be stuck to the surface like a helmet, windscreen, surfboard or something similar.

When you then attach the camera, just slide in the 2 parts to make them connected. 

Note;
Use is your own responsibility.
