It's got kind of an "Andromeda Strain" thing going for it focus wise. Back in the late 1990s, just when the 3-D printing thing was catching on, some shops set up making custom aftermarket parts for model builders so they could add a touch more realism to their creations and Dioramas.

Besides... The Boeing 314 "Clipper" is one of my favorite flying boats.

Similar plane. The Sea Duck was a mythical hybrid of an amphibious Grumman HU-16 Albatross and a Fairchild C-82 packet transport.

Polygon failure. The image was created for a printer less capable of the fine detail to display the triangles. I imagine the files with that sort of details an digital smoothing will become available shortly.

This reminds me a little of the kits available in the 1960s and 1970s that let kids make their own toys. The Mattel 'Thing Maker' series -- my brother has the 'Creepy Crawlers' set; I had a 'Creeple Peeple' add-on set. The weirdest was my 'Strange Change' machine.

I also had a set that would let me melt plastic pellets and make my own injection-molded toys. Probably had ten ways to hurt yourself...
