This tickled an old memory... while some of those are classic designs, I don't think they're the old ones that I had as a kid in the 80s.

So I looked. I think it was things like "100 paper spaceships to fold and fly" ... I'm sure there were other ones that were associated with various sci-fi lines.

But I also found https://science.nasa.gov/astrophysics/resources/documents/un... which has paper models of such spacecraft as JWST and Kepler.

Now THIS is what the Internet was supposed to be about! :)
