Thanks guys

I guess it's theoretically possible to unfold higher-poly models , but they easily get very complicated and you'll have a really hard time folding and glueing them into shape. This one already took long enough to put together. The old models are actually quite suitable for making paper models because of their simplicity.
About plastic parts: I have actually been thinking about putting my hipoly models for sale at shapeways, a very nice 3d printing site. They can print models in materials like polyamide, stainless steel, or a full color gypsum based material, with precisions of up to 0.2mm. Only problem is that, since we're doing teamwork, some of my models are based on other peoples work, although I guess I could simply put my markup fee to zero on those models (the pricing consists of a material fee as well as a royalty markup fee which the user can freely set to anything he wants)...
3d printing is of course not as cheap as mass production molding, but you can get fairly small models for a few euros/dollars. If people are intersted I could propably upload something
