D² - Modular parametric car

Note:The design of this car is not only mine, but also from Thingiverse user davansan ( http://www.thingiverse.com/davansan ) This is a car made for a competition on our college, "Universidad Carlos III de Madrid". Our first thought was "I want a car that I can modify without having to print the whole thing again each time", so we designed a modular vehicle, composed by several parts, totally editable, and with the posibility of expanding it in the future. We also designed it almost totally parametrizable, so it is easy to adapt it to each ones necessities. The base of the vehicle has some rails in which you can insert new accesories to improve the vehicle.
