These boxes are designed for K&F Concept filters. The bigger one is used for my variable ND filter and the smaller one for my CPL filter.

My filters are 58mm in diameter. I had to scale them up 1 percent to fit. I designed them to be scaleable to your needs.

No supports needed

I printed them in matte ABS plus from Esun

Use a layer hight like 0.1mm to get perfect threads
