This is a handle designed to work with my cage for phone photography or small mirrorless camera. It uses the NATO rails on the side of the cage to lock the handle. It is designed to be used with only one M4x16 or M4x20 screw. No tools required exept for something to press fit the screw into the knob (ex: small hammer). There are two versions. One with a textured grip and one with a clean grip. Can be printed in any material, but PLA is the easiest.
