Description
Somewhat parametric, kinematic mirror/lens mount for steering optics.
en.wikipedia.org/wiki/Mirror_mount
It contains a living hinge in one corner and two magnets in the adjacent corners. These magnets are attracted to a pair of set screws used to adjust the mirror angle. The size of the magnets match those in the makerbot platform.
There are both imperial and metric mounting versions. Imperial uses a 1/4" hole, while metric uses a 6mm hole to match the optical benches. Alternatively if you need a cheap optical rail you can use T-slot extrusion like I did in the photos.

Instructions
Print, cleanup edges, press fit two M3 nuts, press fit two 3x3x3mm magnets, and screw in two M3 mirror adjustment screws. Some superglue may help keep the magnets in place.

Brilliant! We are just putting the finishing touches on an optical rail system for Open Beam. Sweet mirror mount -- thank you! We are definitely going to use it.
Thanks, I'd been sitting on the design for a while.. I noticed your work and realized that I should post this sooner rather than later so that hopefully you can use or modify this design rather than starting from scratch. I'll upload my Michelson interferometer soon :)
