After spending around $20 thousand, physicist Sterling Backus created a life-sized model of the supercar with his son using just 3D-printing technology. “The parts’ design is based on the Lamborghini Aventador, but we have changed each panel significantly, to add our design flair,” Backus added. “In addition, no molds are made, and none are for sale. This is a one only project, and not for sale.”
