There is a great site where you can download free 3d Star Wars ship models (meshs).

It is my hope that someone with 3d skills would be up to converting them for use in the game, then post them here for the community to enjoy.
I attempted to do this myself but my 2 days worth of 3d experience were not up to the task.
May the force be stronger with you.
