Checking to see if there's any interest in my design for a chin mount for gopro or action cam. I have gone through dozens of prototypes. This is my current model and it attaches with one large zip tie. It could be attached using doublesided tape but I like the option to cut the tie and remove it. If there's interest, I would consider selling the design or printing these off for folks. I currently only have this for size small helmet, but should have the medium large soon
