Once more I am posting my favorite models for download here on Deviant art. You will not find many spacecraft packs for downloading on the net and I remember I was trying to find them and learn how to model two years ago.
This pack is released primary for learning purposes. You can also use them to complete your scenes in 3D.
If you use it you must credit me.
Update: 3DS files added too. Now you can use it in other 3D programs.
