About this 3D model

A "toy" rocket car. Derived from this "toy rocket" http://www.youtube.com/watch?v=TIAwVWGTbzU Still working on it, this is one of the tries https://docs.google.com/leaf?id=0B70l7jshcRPON2RiNGNjMjQtNmQ5Yi00ZDA2LWI5ZGItYWJmZDM5NWVhNTMx&hl=es Surprisingly, the plastic stands pretty well the combustion of the fuel.(Infill solidity 1, the tries without that solidity are not very encouraging...) ****DISCLAIMER**** The aim of this car is to travel 1.5 meters as fast as possible, not being cute nor complex neither perfect. xD
