Photography Filter Case

I needed better case for my 77 mm ND filter, so I designed one. It is designed for cheap ND from ebay (which came with very bad case).

My ND filter is 79.2 mm in diameter and 5.7 mm in height. I'm not sure if it will fit some other 77 mm filters.

Hinge is piece of 1.75 mm filament secured with CA glue. I used 8*3 mm magnets, also glued using CA.

Please let me know what do you think about the print in the comments. I'm considering to make this print fully parametric to fit wide variety of filters and magnets.
