The Paper Model directory has a collection of links to dozens of paper car models, from DeLoreans to Hondas. These are just what you need to populate the streets of your modern era miniatures wargames. As is usual with these, you can use your printer settings, graphics program (that’s what I use) or a copy machine to adjust these to whateve scale you need.
Paper Models
Paper Western Figures
If you’ve wanted to try out some of the outstanding western games that are in print these days, but don’t hvae the figures, you could download and print these sheets of 19th century western gunfighters, animals and other assorted things.
Paper Model of Two Story Warehouse
Martin Gumbold offers a nice paper model of a two story, European “good shed” — what I would call a warehouse, because of the loading dock. There is no apparent scale, but I downloaded it and sized it up, and think it would work very well for 20mm, and pretty well for 25mm – 28mm figures. You could use it for a variety of periods, because there are no obvious things to date it.
Independence War Paper Models
The Independence War Paper Models site has some very nice — and free — paper models of starships.
Disney’s Haunted Mansion Paper Model
This free paper model of Disney’s Haunted Mansion is a tour-de-force. Even if you don’t want to download it, you need to take a look.
