No idea on the printers, but I work in the modeling industry and have the software to create a point cloud and subsequent model of a part easy enough.
Maybe I need to start logging some parts!
We should kick a thread off and give instructions for people to take photos of a part and I can model and post on a public free for use spot in the forum.
I think with project car things there is enough expense already and if we as a group can work together to model some parts that we have laying around, it may help future proof a few of the harder to get ones.
Also if anyone knows of how to get any cad files of parts Toyota may already have floating around and we can put them somewhere.
Just a thought....
