Maybe I'm behind the times but I found this a bit interesting..my 17 year old son bought a car (the Z) recently and one of the center caps off the wheels was missing..it was chromed plastic...so he mocked one up (including the Datsun logo)on some type of Google drawing program, transferred it to a CAD program and then emailed it to the local university to be printed on their 3-D printer. They offer this as a public service and charge 8 cents a gram for the product. It should cost under $2. It will be interested to see how it turns out.

I was shaking my head at this. Is this the future for tools and parts? Print up plastic parts for the trucks?
