Destiny Jumpship Mix 'n Match
Make your own Destiny ship!
Each ship typically has a cockpit, nacelle, rocketlauncher, antenna, and engine (sometimes a body is required to complete the gaps). These are a bunch of models of different sections of different Destiny ships.
Grab several, and merge them in Meshlab (http://meshlab.sourceforge.net/). File->Import Mesh->select files. Filter->Mesh Layers->Flatten Visible Layers. Then File->Export Mesh As-> name file and section/support and print!
EDIT: Please note thanks to the work of Brent Peterson and reddit.com/u/potatob there is an STL generator for getting stls from the destinydb.com site (they can't be mixed and matched, but will have lots of models to work with):
