Cokin Filters Storage Box (case)

thingiverse

I meticulously crafted a custom storage case for my 3 square filters (M(P) series size) and 2 round filters, both also from the M(P) series. As this was my very first DIY project, I quickly discovered a major flaw - the box and cover close perfectly well on their own, but it would be highly beneficial to have some sort of clip or latch in place. For now, a rubber band around the box does an adequate job while I'm on the move.
