(Update: added more adapter sizes)

If you're like me, you have a bunch of threaded lens filters that you'd like to use on your Moment anamorphic lens (circular polarizers, ND filters, etc). Many of my filters are 77mm so that's the size of the STL, but you can also create an adapter to fit any filter size using the OpenSCAD files provided.

The internal thread works pretty well to hold the filter in but you can also press fit your filters if needed. Print at .1mm layer height or below for the threading to work.

You might want to use a very dull filament or consider adding flocking (felt or paint or something to prevent light rays from reflecting around between the lens and filter).
