I love the internet. Now I just need to make my own design that can clip onto just about any average diameter lens without light leaks. This one is okay, but needs redesigned a bit. The cardstock is a sound medium at least. I think I could probably make a thin multiple-aperture box then be able to select whatever blade number and shape I want.
