Is it possible to make a scissor-like hinge out of cardboard? I came up with an idea for a tool to measure how many heads tall a figure is.

Problem is, I don't know how to make the hinges work. What I mean by 'scissor hinge' (I don't know if that's the correct term or not) is a 'hinge' where two long flat pieces (let's just say cardboard for now) have some kind of rotational joint connecting them that let's them move like a pair of scissors. 

I don't know how I can make such a thing. I'm sure that this isn't a new idea, but I'm certain that even if someone is mass producing these, that crafting one myself would be much cheaper. But I don't know how I can make such a hinge out of cheap materials. I mean, I'm building this thing out of cardboard (specifically the cardboard of a cereal box). And the thing will need a lot of these hinges. I estimate probably 31 will be needed. And its not that complicated of a device either. Its more like... a chain of simple devices. Also, this tool will have to be pretty small to make the measurements I need. So that also limits what kinds of materials I could use for the hinges.
Small brass eyelets could be quite durable in this application.



These are sold for card-making and scrapbooking and used to appear on certain kinds of office supplies in very similar applications. They might also be sold at leather crafting outlets.

They would require a hole be punched in the cardboard first, for best wear characteristics. Also, how far you set them is critical to getting the right resistance to rotation of the two cardboard pieces.

Their use requires a punch and die that would be sold at the same place for a few dollars. It's possible there is a pliers-like version as well.
