GoPro mount brace

Whenever I mounted my GoPro to my shotgun no matter how tight I made it every time I shot the camera would move down making the video useless. This is a basic mount I designed to solve that issue. I tested it at the range and it withstood the pressure without so much as a crack and the GoPro didn't move a mm. My friends mount has a notch sticking out so I added a notched version. Printed in PETG but if it's not going to be laying in the sun then PLA should be fine.
