These filters come with a sticky patch to hold it on the ZMP camera. The sticky material leaves residue on the camera and makes it very hard to clean the filter lenses.

This retainer will hold the lenses without need for the sticky stuff so take it off. Once the retainer is placed on the ZMP camera filter lenses can be swapt out easily. If you like you can leave the retainer on the camera without a filter as well.

I used ABS because it has a 15-20% lower density then PLA or PETG.

Part B (the hook) comes in 2 sizes. The longer one holds a bit more firm but is also harder to remove after use. Pick the one you like the best. Push the hook all the way through the loop on part A. You might need to sand down the end a bit to get it going in.

Part C needs to be glued to part B in such a way that the JSR lens can slide in. Make su
