CNC queue means 3d modeling/printing

I have all the files and materials needed to CNC my 4 car parts out of blue foam but need to wait until the machine is free. i am using my time to model aspects of the car i intend to 3d print. i have previously created a Brembo disk brake for the 3d vis unit of my degree which i will use but i have also been working on creating an alloy. I have found a Recaro seat for free download on turbosquid.com which i aim to print and adapt in a physical form before moulding in order to cast 2 unique Recaro race seats. I may find other interior aspects lend them self to 3d print technology but until i get close to the interior modeling next term im just biding my time with this until i can begin sculpting.
