Yes, I know it doesn't close all the way. this is by design.
The first iteration of the giant mechanical iris in my home turned out to be somewhat pointless in its current position. When one of the leaves broke, I decided it was time to re-think the design. and location.
I have a 2nd story room with an access panel for getting furniture and things in place, and I thought this iris would be a perfect fit. I was obviously inspired by the cupola on the international space station (and the millenium falcon)
