However, I found a nice Porsche 356 body on Thingiverse.....and downsized it a bit.

It is slightly smaller than the Ninco:

But it's pretty close, and I am going to at least give it a try. I can always upsize it a bit if needed.
I am pretty psyched to get it running. It's pretty flexible so I am not sure how durable it will be, but that's the fun of the first test, right?
