Camera filter case

A simple case screw lock for one 49mm camera filter with. The case is specifically tested with 49mm Tiffen filters (black mist pro, glimmer glass, UV, polarization). The case has internal dimensions: diameter 51.5 mm and height 8mm. 

The model can be scaled to house other filter sizes/brands. Note though, that it must be scaled uniformly in the XY plane and cannot be scaled “too much" in Z since the screw threads most likely will not work that well if scaled to some insane height. But it should reasonably handle scaling for most normal sized camera filters.
