Many moons ago, TSR / Wizards of the Coast released a series of paper buildings for use in D&D games. They’re now available free for the downloading. Any medieval / fantasy wargamer will find these useful. I think they’ve really stood the test of time.

Warhammer 40K Chaos Warhound Titan Paper Model
Given the absurd prices on Warhammer 40K Titan models, this paper model of a Warhammer 40K Chaos Warhound Titan may be just what you needed.
Ancient Aztec Temple Paper Model
Here’s a paper model of an ancient Central American style temple, just ripe for sacrifices. I think it would be terrific for a pulp action game.
Fantasy Paper Miniatures
There are just too many good 2.5D fantasy miniatures on Eddnic’s site to begin to list them. Visit and take a look.
Post Apocalypse Car Paper Models
Greywolf offers a large selection of paper models of post-apocalypse style cars scaled for 15mm/20mm as well as a few designed for 25mm / 28mm. Scaling the figures with a printer should not be a problem, though.
