Making the quick magnetic snap camera filter | 3D Print

The quick magnetic snap camera filter makes filter changing easy and fast. I need to change ND filters frequently. The screw-on filter is very slow, so I designed and 3d-printed this magnetic snap-on filter. Made my life much easier.

Now, I only need to buy one size filters, and use them on all the lenses I own.
Female adapter is for mounting all the filters. Male adapter is used on the camera lenses.

顺便提出两个疑问，那么岂不是要用固定 ND，再一个广角会不会有暗角，因为 ND 和镜头（本身）的镜面面有一定的间隙。
