UPDATE

I made a final version with improvements from what I learned on the first one.

This one is now 105mm with zero vignetting at any focal length. Again I started with a clear filter, molded the Sugru to it, this time leaving a gap around the lens barrel that I filled with a foam strip which makes the holder nice and snug on the lens and light tight.

I streamlined this one, making it quite a bit shallower than the first one, cutting off all the excess length that wasn't necessary

1 inch thick

Nothing left to do now but shoot some long exposures at super wide angles!
