FWIW, HG Wells' novel The Time Machine is public domain. I'm sure a model based upon his description in the book would be legal to distribute.

Hello, i have seen and used some of the D&D stuf put out by this company, and must say i like it, but somehting that has been bugging me for a while now is the general lack of Sci-Fi flavored designs and am hopeing that you will do a good job on it.

I am putting my vote in for largley "accesory" style peices.  Some corridors, computer consules large stand up wall jobs as well as ones like islands (think kitchen islands), power generators, hyper/warp drive, gun stations, pilot stations, bunks, tables, big command tables, holo tables, work benchs, confrence tables, video consules, etc. anything that can be used to add cover and go inside a room.

While many people have suggested drop ships etc, those i don;t particularly care for, however hover craft/land speeders, trucks, some smaller "fighter" scale ships etc could ver very nice.  I freely admit i want these items formy SW RPG (and later for the SW mini game) and would very much want a more Star Wars look to it than a Star Trek Next generation look...  

I second Genhis notion:

Gimme Staw Wars'esque corridors and docking bays.

I use paper terrain for RPG and as tabletop scenery, so some kind of outdoor terrain would come in handy, too.

Maybe blocky turbolaser turrets and raised landing plattforms.
