This replaces the chest strap (buckle housing) on any suitable backback with the opportunity to mount an action camera on it.
Additionally, you need for attaching the action cam (upside down) the 30mm arm and the axis change connector and some M5 screws (which should come with your camera)
As it is not tested for strenghtness I secured the whole thing with another strap on the long slit (you can use a rope or zip tie as well)
I printed with the "Tree support" in Cura. It was very easy to remove from the inside of the buckle housing.
