Larger than the K-class deep space stations, the D-class starbases have extensive facilities for storing deuterium fuel and other necessities for starships on long duration voyages. Two large hangar decks can accomodate more than one hundred shuttles and other small vessels.
The 3D Model
Built using Carrara 5, Hexagon 2, textured using Paintshop Pro 7, rendered in Carrara and Poser.
The download is free. You can do anything you want with it, and I don't require any of those obnoxious credits to be plastered all over your beautiful renders. I used Poser 6 in the creation of the files. I have no idea if they will work in different versions.
If you download this and find that something doesn't work, you can send me an email and tell me what the problem is, and I'll do my best to fix it.
