It was made by Doug Drexler... you may recognize the name from several of the old Tech Fandom booklets. He made it as a professional, and most notably designed Enterprise NX-01. He also did the CG for the first two New Voyages (now Phase II) fan films.
As I recall, John Eaves did the initial design sketches for NX-01. Doug I think built the first digital model and added all sorts of little details to the exterior. It's still impressive work, as he was originally a makeup artist, lobbied for a transfer to the art department, and learned how to use 3d software on his own time.
And thanks for the cutaway image, I drooled over it in the episode but couldn't get a good screenshot of it.
