Low profile rotational mounts

thingiverse

These ultra low profile rotational mounts are designed for the most demanding of applications where space is at a premium. Typical applications are for waveplates and polarisers in a laser system. One mount accepts a 5x5 mm optic up to 3 mm thick and the other takes a standard 0.5" circular optic up to 2 mm thick - use a little spot of epoxy to hold the optic in place and you're good to go! Both have a beam height of 0.4625" (11.784 mm) in order to be used seamlessly with Siskiyou mirror mounts (we used their IXF.50TA mounts). The top of these mounts capture an M2 nut so that an M2x6 screw can secure the mount in place after rotation. Bonus: if you use nylon nuts and screws the whole mount is completely non-magnetic. Nice! Instructions Glue your optic in place with a couple of spots of epoxy in the pockets within the model and allow these to fully cure before assembling. Try to make sure you keep the optic as flat as possible when you glue it in. Press an M2 nut into the rectangular hole the the top of the mount - it should only fit when oriented flat-to-flat (this stops it rotating when in use). Add an M2x6 screw through the top hole of the mount and you're ready to go! Protip: Print the retaining ring pieces in different colours for polarisers and waveplates so you know what they are at a glance.
