Optical mount for lens / mirror / prism

This is a kinematic optical platform mount designed to fit onto a regular optical breadboard using 1/4-20 mounting holes (or metric). It uses a mounting arm (PM1 style, see separate PM1 file ) to hold a square optical component against the lower platform. It uses 6-32 screws with knobs to control the movement of the platform left-right and pivot up-down. Mounting screw is 6-32 and can mount onto a steel 1/2 inch post with a 6-32 thread, or a 3D printed post (see separate file). The component requires a number of metal parts:
