GoPro 52mm Filter Adapter

thingiverse

This is an accessory designed for attaching 52mm photography lenses to a GoPro Hero5, Hero6 or Hero7 camera. To use it, simply push the adapter over the lens protector on the GoPro and then screw in your preferred 52mm lens. I fabricated this adaptor using PET-G, which may initially make the thread feel quite tight - be cautious not to cross-thread, as this can cause problems. However, after several uses, the thread should loosen slightly. I've added a grub screw hole at the bottom of the adapter for extra security - while the fit is already quite snug, using a grub screw will keep everything firmly in place. Note that applying a grub screw may leave a small mark on the edge of the lens protector.
