So to start, we had the usual drilling of the body cap.
I had some decently thick poster board from a failed Halloween endeavor, and made a sleave to fit around the lens. I also cut small slits into it to serve as guides for the two screws that protrude from the lens.
This seemed to be the final step and all was good, until I accidentally pulled the lens out of the sleeve, and tore the paper while attempting to fit it back in. Annoyed, I opted for a much simpler approach. I fit the sleeve to the cap, not the lens. This left a decent amount of room for the lens to slide in and out of, so I padded the lens with a few rounds of electrical tape.
All said and done...
