A night of great progress

Didn't get started until around 8pm or so tonight, but made some great progress on this project. I picked up some 1" insulation foam at the hardware store to do a test run of the design. Worked great. After it was cut I compared it to the original. Very close in size, but not there yet.

I made a rookie mistake. When I drew the profile line of the design, I think moved OUTWARD from that line for the trim ring, rather than inward. As such, my design is too big by exactly the size of the trim ring. I need to swap the trim ring to be on the inside, and it should be nearly an exact fit.

I also didn't mill the inside as deep as the final design to save on cutting time, since I'm primarily concerned with outside size fit at the moment. Will try again in the new few days and then test fit. I also used a 1/4" bit for the entire thing, so some of the rings couldn't be fully cut due to the distance being less than 1/4" between pieces inside. But for now, some eye candy:
