When strapping GoPros to our quads using wedge-style mounts, whether they be printed foam or carbon fiber based, we're leaving the cameras totally unprotected. This little hat slides on your battery strap and fits over the top of the camera, offering a fairly minimalistic and light weight solution to that problem. It's obviously not going to protect the lens in the event of a head-on collision, but I got sick of watching the top lip of my camera be slowly eaten away by concrete every time I crashed.
Print face-down without supports.
9/11/17 - Just realized I'd never added the other version, the one that I've actually used since day one, that removes the bit of the mount from the camera's view. Added that file named Hyphy_Hat_v2
