Glass Filter Cases

A simple plastic case for holding multiple filters screwed together. I wanted something small and lightweight to protect my filters when backpacking with my Intrepid 4x5. It's a fairly simple design - just two hollow cylinders that fit together optionally with a cutout to hold a rubber band. I found without the cutout the rubber bands don't like to stay on.

Items were made in FreeCAD and I've provided those files for further modification.
