Bill shared this Hemmings article that discusses the use of an iPhone as a scanner for car 3D parts. I know that for several years there have been some Willys wagon knobs and other items 3D printed and available for purchase.

But, to take that from a hobbyist endeavor to a commercial scale, with mechanics or parts resellers producing parts with 3D printers in-house is an intriguing idea. Practical? Certainly not now for multiple reasons, but it’s not a stretch to believe that car parts for vintage vehicles will only become more difficult to find. So, I’m hoping that some magnitudinal advances can occur in this arena.
