Starfleet Command Shuttle, SC-4
The future Admiral Janeway's personal command shuttle, outfitted with stealth technology, an ablative armor generator, and various other future technologies.
Computer, deploy the armor!
USS Rhode Island, NCC-72701
A Nova-class variant commanded by the future Capt. Harry Kim. Thankfully easy to model and to texture!
USS Enterprise, NCC-1701-J
USS Federation, NCC-2100
Here commemorating the upcoming release of the Star Trek animated series on DVD (waited a long time for that one!) with its simple textures is Franz Josephs’ Dreadnought-class starship, probably the first really popular non-canon ship in Star Trek fandom. You need to build the nacelle superstructure first, before assembling the primary and secondary hulls. I recommend a mix of heavy cardstock for the superstructure and secondary hull, and lighter cardstock for the saucer and nacelles.
Shuttlepod 1, USS Enterprise NX-01
The first one I finished designing, and to date the only one I've actually built! With 250 GSM cardstock, the structure turned out pretty stiff even without internal bracing.
USS Excelsior, NX-2000
My first attempt to use textures from CG orthographic drawings made from a 3D model. I decided not to have an indent for the deflector dish to simplify the shape. While there was less mirroring here, the other problem that popped up was inconsistency in the brightness/saturation levels between different parts of the image.
USS Titan, NCC 80120
This was a quick design using 5-views that were apparently handrawn using graphic software. The measurements were not always consistent; even though they were visually okay. The resolution is not ideal, and I overlooked some places where the texture maps didn't align properly. And the saucer turned out to be egg-shaped rather than circular or elliptical, which gave me some problems with the hexagon I used for the primary hull. This needs a lot more work!
