2" Filter Holder with optical Post

An 3D printer holder for 2" optical filters like the NE2Rxx ND filters from thorlabs.Just put the filter into the holder and use the screw to tighten everything (slightly). If the filter has an SM2 thread, it will be exposed partly at the front of the holder so that you can screw another filter on top of it.Includes and post for easy mounting in an ½ inch post mount on an optical bench.Should only be used with components like filters where the exact positioning and orientation is not that critical.
