Filter Case, 67mm

A case for 67mm photographic filters. It uses 8mm X 3mm (diameter x thickness) neodymium magnets for closure. This is a remix of my 95mm case.

I found I had filters of various thicknesses. I modified the design of the case bottom to accommodate the different thicknesses, so the magnets will strongly hold the case closed. There are bottom STLs for 7mm, 8mm, 9mm, and 10mm thick filters. You can use the thicker versions for all of your filters, or customize and maybe get an extra filter into your camera bag.

I designed it to add the magnets after printing, using epoxy to glue them in place.

Magnets - 8mm X 3mm

Take care to ensure that the magnets in the corners are all oriented the same way. Failure to do this will result in problems, such as the lid only working when turned a particular way. I prefer using a 2-part epoxy for this, as it will adhere to the magnets and the print and produce the strongest bond.
