Hi all,
I got reply from Dan Gray of sidereal technologies, who was visiting Mike and Ann Rice from nmskies.com (New mexico skies) and they kindly supplied the info I needed.
Poita has 3d printed me a smaller scale model of the secondary, and I think the concept of 3d printing will work very well.
I am designing another version that has a plenum chamber in the baffle that has nozzles which will blow air over the secondary mirror, to prevent dew forming and thermal surface eddies which will minimise telescope induced seeing issues. We'll see how that goes.
