Carter3D is a cool Shapeways outfit with a whole bunch of neat ships. There are quite a few Star Wars designs, but there are also about a dozen detailed Wing Commander models available to 3D print. Carter seems to be a Prophecy fan, but there are also a handful of ships from WC3&4 mixed in as well. They're not colored or textured, but both white and frost material is available to facilitate your own artistic painting. The WC craft are linked below, but there's also one interesting mislabel. The Wing Commander Missile Destroyer is actually a Macross ARMD carrier, which then bears quite a bit of resemblance to the Academy television show's Achilles. It may very well have been the inspiration for the WCA design. You can find all the designs here. Thanks to Whistler for the tip!
