3D-printed kinematic mounts based on the ball-and-screw design outlined above have been reported previously. However, our efforts to miniaturise those designs to fit within our narrow optical cage assembly were largely unsuccessful. The miniaturised mounts were awkward to assemble, and even small printing defects in the ball-bearing sockets caused substantial mirror drift and wobble. Our preferred mirror mount is based on a much simpler kinematic mechanism due to Pekelsky that uses a short length of thick, stiff wire in place of the ball-bearing and extension springs. The two ends of the wire are press-fitted into facing holes in the two plates and the wire is lightly bent so that, in its resting configuration with no externally applied forces, the corner of the mounting plate diagonally opposite the wire is pushed towards the base-plate. Hence, with the screw tips in place, the wire exerts a restoring force that keeps the screw-tips in permanent contact with the mounting plate. The use of a wire "pivot" greatly simplifies fabrication of the kinematic mount, while still providing excellent structural rigidity and a wide travel of several degrees in each direction.
