This piece helped me with my GoPro. Sometimes I want to shot timelapse in portrait mode, but I could not find any original GoPro mount to do this. So I decided to create this mount and i'm very proud about the result because it fits perfectly with GoPro accesories (like tripods or pole).
To do this piece I setted the printer like this:

• 0.1mm for the resolution
• 100% fill

This piece is not threaded. You need an hex nut to fix the GoPro screw. I found it between my GoPro accessories.
