Made a mount for gopro hero 6/7/8 etc. because I did not find any that was nice and small and had a bottom plate that would allow me to screw in the mount to the frame rather than zip tie or velcro it on.
I made a tiny alteration to the STL file after printing the mount in photos. The camera should now slot in so that it protrudes the same amount on each side.
In the future I might make a window for the front screen. I made some design attempts at providing some better protection around the lense, but I am not proficient enough at designing to have come up with something that was satisfatory.
EDIT: uploaded the Fusion360 file after attempting some alterations with the front screen window and extruding to protect the lense. Moderately successful modification I probably prefer just the stl file that is also downloadable.
