This works for all session style GoPros!
I made this box to protect my Hero 5 Session when carrying it around in my backpack or golf bag. It uses a 2mm rod for its hinge.
I recommend printing the lens protector ring out of a rubbery material like TPU but really any material will work just fine. Its purpose is to keep the GoPro lens from scratching against the bottom of the case.
For best results, go with a low resolution like 0.1 mm. By switching out filament colors during the print I could achieve a nice multi color effect. Please let me know if you like my design!
