This is Punchy, the Robot-Buggy-Tank-3 Wheeled-Thing. He was made for my mod, Unreal4Ever, as a vehicle with physically attacks. Yup, he's a tank that punches other tanks! Or he would have been, but all of the programmers kinda took off at that point, mostly because Epic Games kept stealing our ideas without any credit and never promoted us.
Recently, when I was combing through my old models looking for something to make into a Toy through Shapeways, I found Punchy and resurrected the model. Punchy might never be in a game, but at least he'll live on as a cool Toy Kit.
His arms are held in by friction. The shoulder joints are so tight, a little sand paper might be necessary just to fit them in. The back and front wheels spin freely. A small bit of super glue attaches his neck joint to the body, as well as the Engine and front wheel spokes. The parts all arrive white and require some dusting. I'd suggest dusting, and then painting him completely, before gluing the parts together!
(Note to buyers, he's pretty large, so that $135 is almost all going to Shapeways. I earn enough for a hamburger and fries.)
