What if it was made out of an erector set? Then after that you moved to a hand crafted duct tape garage prototype? Then to a small scale SLA prototype to model it's characteristics. Then maybe a scale replica using CNCed parts? Burt Rutan used to build small scale models of his concept planes and mount them to the roof of his car to test their aerodynamics. Last time I checked he managed to turn that "Lego" project into a manned space vehicle.
