I only discovered this thread today. I was trying to find info on a 66-inch Enterprise I saw occasionally on Facebook. I have finally decided to make my own model at this scale and I found a site (some time ago) that had the files to do a 5-footer. I sized those files up to 110%, for my 66-inch version and began printing the saucer. I have a Neptune 4 MAX printer and I've done some pretty neat things. But, I really just wanted to say--
Your 11-foot model is just plain JAW-DROPPING!!! I read through this entire thread today-- fascinating! The single question I have for you is simple: Are your 3D files available? There are problems with the ones I'm using now, so I just had to ask!
Congratulations!!!
