I didn't know of the commissioned project (Dave, excellent job), but I did see the one over at ecardmodels.... I still wanted to do it on my own.
Dave, what scale is yours? I'm intending to put a good bit of detail into this one, as I wanted something suitable for sitting in a display case in a local museum.
I too have had a few people ask (with money) for me to design this one... and since I wanted it as well made it a no brainer. I haven't figured out yet how I can release it after taking a few dollars for it.
I worked on carving up the lower hull beneath the saucer last night (which I liked). I also did the struts and blisters... I will be redoing those. I didn't think about how to build them as I moved stuff around on the screen.
