The Star Fury space fighter from Babylon 5.
One of my favorite SciFi ships, ever. Star Furies look like they could actually function as a real space craft. The ship is basically a set of engines and reaction control thrusters mounted as far from center as possible, with an upright pilot (the better to handle high-G acceleration) and a bunch of guns in the middle.
Split and arranged on a plate for easy printing. There's a few bits that could use some support to print out perfectly, but the plate will print OK without it.
