The "Jimmy Hill" GoPro session helmet chin mount

"The Jimmy Hill"
This is a mount I made to fit a GoPro session to my motorbike helmet (Shoei GT Air) using the origional camera mount cage.
Requires the mounting cage, screw and nut.
I originally made The "Jimmy Hill" Polaroid cube helmet chin mount and decided to try modding it for the GoPro, resulting in this design.
To use this you will need to remove the chin wind skirt from the helmet, or cut a small hole in it.
This may work on other helmets depending on the shape.
