On <a href="http://www.geocities.com/tormento_khan/trek.html">my Coda Star Trek RPG</a> website, I have listed 5 pages of tent-fold, paper miniatures I created.
Be warned, they're largish JPG files (1.06 to 1.78 MB), ZIPped up (ZIPped size is 798 MB to 1.38 MB).
The view is top-down, and in some cases, with very square ships I actually split the view between two "panes", but I think the overall effect is acceptable.
The miniatures produced so far will probably work best for later movie-era, TNG, DS9, and later eras. Sorry, the Classic series and Enterprise are great and all, but not my cup of tea for roleplaying game settings.
Let me know what you think, if they're at all useful, etc.
