Build your own mini Klingon Bird of Prey out of this laser cut thin metal sheet! The 3D model starts off with a small 4 inch sheet of very thin metal that as been cut and scored. Just follow the enclosed instruction sheet to pop out the pieces, bend the tabs and connect them to form you ship. Because they are made with the thinnest of metal, they are very lightweight and pick up the light as they move. Maybe put on on a spinning base or hang one near an air conditioning vent to watch it fly through space!
