Couldn't find any 25 degree GoPro Hero 5 Session camera holder that I would be happy with, so I made my own.
The holder uses the screws that already hold the top plate, so you just put it between the screws and the top plate.
Should fit any strap that is 20mm or thinner.
It is designed specifically for the GoPro Hero 5 Session, I am not sure if the other versions of the Session cameras have different dimensions or shape and if they will fit. (Leave the comment if it fits well so I can edit this description, thanks)
0.2 layer height should be enough for a working print.
The model can be printed without any supports.
