No need to assemble! 3D print full on the spring of the toy car

When I was young and not so much on the tall toy, with a wind up toy, car or animal (the most impressive to the number of frogs), this is enough in front of a buddy...... recently, a man named Luke Ditria Australia students in Shapeways can be released a clockwork toy car he 3D printing, printing one-stop complete without assembly, and internal gear structure at a glance. It is also equipped with a wind up key, after the car back to wind it up, let go after the car will run forward.
