About this 3D model
Print your own thumb screw for Gopro. Match the Gopro accessories. The design is for 30/35/40/50 mm long M5 screw with hexagonal head. The first screw insert need to be done with power (or just tighten it into an open nut). *Notice that the 30 mm screw is too short for use as the camera screw (the 35 mm version might be as well, I haven't printed it yet), the 40 and 50 mm are fine there. *The 40mm version is in the size of the original screw
