Two versions of the filming miniature were built by Industrial Light & Magic (ILM) for the first season: a large six-foot model and a smaller less-detailed two-foot model, both constructed under the supervision of Ease Owyeung. Both were capable of saucer separation. The cost to construct the original models was $75,000. For the third season, Greg Jein built a new four-foot miniature. It was not built to separate, but for the first time it accurately depicted the Ten Forward windows. It first appeared in TNG: "The Defector" and completely replaced the previous two models, although stock footage of the original models was still used. The six-foot model was briefly reused for the saucer separation in TNG: "The Best of Both Worlds, Part II". It was completely refurbished and overhauled for Star Trek Generations, where it represented the Enterprise alongside a computer generated version and a special twelve-foot wide saucer, created for the crash sequence. ILM crewmember Bill George relabeled the registry on the saucer to "NCC-1701-E" before the model was returned to the Paramount archives. The four-foot model was modified into the three-nacelled Enterprise from TNG: "All Good Things..." and later restored to become the USS Odyssey in DS9: "The Jem'Hadar" and the USS Venture in DS9: "The Way of the Warrior". It may have also been labeled as the USS Trinculo at some point during DS9's run.
