I don't have a 3D printer (yet?), but I have a 3D printing dream: I want to print all the spaceships we all know and love, from various sci-fi universes (FS obv, but also Star Wars, Star Trek, Homeworld, BSG, Mass Effect, etc), all at the same scale, so you could compare their relative sizes.
I'm thinking that the best number would be a 1:10,000 scale, so a 717m GTCv Deimos would come out 7.17cm long, or a 1.6km Imperial Star Destroyer would be 16cm long. That scale covers most of the beloved capital ships, with the Normandy SR-2 being on the small end at 216m / 2.16cm, and the Homeworld Mothership being at the larger end of things, with a height of 2.138km / 21.38cm. Sadly, the Death Star remains well outside the realm of printability, with DS1's 120km diameter coming out to be 12m "printed" at scale. O.O
Anyway, I haven't begun the project in earnest, mainly because I don't have a 3D printer yet. I've done a bit of poking around to see if anyone's already done something like this, but I've come up empty. Is anyone around here more involved in the 3D printing scene, and has perhaps heard of a similar project?
