"GoBro" Racecoptermount for Super-Old Go Pro Hero

I had this Kind of super old GoPro where you can´t take the Camera itself out of the case, just swap the door of the case. So i designed this thing. This is the Final Version which i havent tested yet because i don´t know how to print it best. Remove the Back door from the GoPro Case, and click into the Upper Rail instead - works fine. Mounting Hole Spacing is for my LHI220 Frame.
