I knew about this kind of papercraft from paperhammer, that is, using models like this in Warhammer tabletop. This makes that hobby accessible if you don't have too much money to spend.

If you are interested in this also search for poorhammer. These kind of things are refreshing in a world of hobbies that are more concerned with buying stuff instead of using that stuff in the hobby.

Also, lovely 90s web design.
