If you like Star Trek minecraft builds then I would like to suggest that you check out my builds. LINK TO SITE
Each of my builds are to scale, fully explorable with complete interiors and include such ships as the Constitution, Intrepid (Voyager), Nova, Oberth, Miranda, Federation, San Palo (Defiant), along with a few kit bash ships such as the Yamato, Longbow, Augustus, and Picon.
Each build is downloadable in either a schematic file or world save. (Hurry, once you update to version 1.2 MC, you won't be able to use MC edit until, and if, it is ever updated again.
