3D Printing for mainstream producers?

I had an idea the other night. Many O scalers and O gaugers are always complaining (especially with a new catalog release) about how the big 2 (Lionel/MTH) aren't always prototypically accurate on the smaller details of their models (e.g. the E-L #1700 SD45, which is actually an SD45-2). What i(f) MTH or Lionel created a web-based portal where hobbyists could create CAD models of their desired engines with prototypically accurate details, then had MTH 3D print the shells in plastic or metal?

I do not believe it will happen because of the time it takes to create the CAD the cost would be to high no one would be able to buy it.

create your own and print it your self would be a better thing.

these places are supposed to make it easier to create and share designs.

Lionel had a pretty nice looking 3D printed Reading T1 4-8-4 in their booth.  It wasn't a running train, but not a bad print job.

I currently working with a designer on shapways on an SD24 project. If this works out and with the latest 3D printing technology we will have a very accurate low nose product. 

Sounds like an interesting idea.
