Camera adapter for gopro filters

thingiverse

A buddy of mine has taken photography as a serious hobby. He had some GoPro Hero 3 filters (which are designed to snap onto part of the case that covers the lens) and wanted to be able to use them with his regular camera. This is an incredibly simple design, the round part should fit around any pocket camera's objective of 44mm diameter. The rectangular side has the size and shape of the GoPro Hero 3 lens cover, so any accessory designed to fit that should work perfectly. The rails and nudges are made specifically for his particular filter (PolarPro), but I don't know if they're standardized or not. In either case, they shouldn't be a problem if they're not needed. I printed this design in FLEX with no supports at all.
