Diecast Direct in Frankfort, KY had some simple pre-made 3-D printed parts in 1:50 scale when I visited their store last week. 3000toys.com in MO & DHS Diecast in OH also have simple pre-made 3-D printed models in 1:50 scale. By simple models, I am referring to trash dumpster, traffic cones, porta potty, etc.,, stationary diorama / layout accessories without many working features.
These are just my opinion,
Thanks,

Yes, diecast direct has more 3-D printed products in every catalog now. They are up to nearly a page of stuff and I won't be surprised if in a few years it is a whole section in the catalog. They are the only retailer I know playing here, but I expect others.
Someone - it won't be me - is missing a wonderful opportunity to build a site where folks could go and "design" their own building: pic the size, shape, outside surface (bricks, clapboard, type of roofing), select and position windows, then when satisfied, select print, see a price, and decide you want it and pay for it.
