Gopro session mount. 30 degrees tilt. Easy to mount. Good protection of the camera.
I use it for race-videos so it need to be solid. Because it mounts under the carbon sidepeaces, the screw holes does not rip open when it crashes.
Print in TPU. I printed it out lying on the side, with support set to "every where".
