Many cities have a art Co-op where you pay a 30.00 or so membership fee and you have access to 3D printers, ceramic ovens, CAD software and such. I've made a 1/18 Typhoon, Tempest, F4 II, Me-163 and others. I had a Harrier II before Merit. I also have made an assortment of different munitions.
There are now also companies that will print a part for you for a small fee and the CAD software is easy to use and free. It may take 15 pcs to assemble, but for 300.00 you can print and assemble your own whatever. Living close to a College of Art and Design helps...
Pretty soon we will all be able to make our own models with ease. My 3D printer can make a great model of any item the software can handle. I make mine with gear retracted and a not to detailed cockpit because who seriously looks inside the cockpit on a large scale model.
Currently I'm working on a 1/18 He-163 using Solidworks, but there is much simpler stuff out there for free, such as

Go for it guys, try to make your own 1/18 model. An easy start would be a V-2.
We are poor little lambs, who have lost our way.. Baa... BAA ..baa..
