... for slotted cardboard used to make 3D forms? The simplest is the interior of a box that holds a dozen wine bottles. The cardboard is slotted halfway on each section and joined together.

Is there a term for this? Some years ago, I ran across an article in a magazine where a man created figures and animals using this method. I tried googling various terms, but not much comes up.

Does anyone have any ideas what it would be called, if such a term even exists?

No, it doesn't have anything to do with survival, but the people here are the brightest I know, and if YOU don't know what it's called, no one probably does.
