GoPro 4 67mm lens adapter

thingiverse

I carefully crafted a minimalistic lens adapter tailored specifically for my GoPro 4 and a 67mm macro lens. To connect your lens, simply screw it on tightly and adapt the thread to your liking. Reducing unwanted internal reflections is easily accomplished by printing with black filament or carefully applying black paint inside using a marker. Achieving the best results requires manually adjusting the extrusion setting to 0.5 millimeters for optimal quality.
