Thorlabs MFF102 flipper centre axis mount

I needed to apply a counter-torque on the rotation axis on a Thorlabs MFF102 flipper mount, and there was nowhere to apply this force. Therefore I created this connector which hooks up to the spare mountpoint on the flipper and creates a central point to connect something using a countersunk M4 screw. For instance, you can hook up a standard optical post with the M4 end, and use that to connect other optics.

Also included is a bracket to mount something directly onto the spare mountpoint itself.

I also included OpenSCAD sources.
