Might as well add my story.
I own a hobby grade 3D printer which I use to print everything from gun parts to Engineering Prototypes for work to household items.
So I am following through with making a 3D graphic of the Elio P4. It's going a little more slowly than I first estimated. This is because I'm doing a better job than I do for my vehicle concept work.
I only have 2d drawings to go by, and I didn't have a top view to start with. I could still use one, either a blue-print or a photo, but it has to be directly center from above.
Then I will try and work with SG, or will find a 3D print service and get a price and other details required to 'print'. I have even seen ones that take Sketchup files direct to print.
It may take a couple more weeks to finish this, I only can work on it in front of the TV a couple hours before bed each night. I'll keep you posted, and put up 2d snapshots in this thread as it progresses.
