Really practical hobby. Imagine it’s way way quicker to iterate on prototype designs with cardboard. But didn’t know this was a thing beyond that.
My mind instantly goes to thinking central planners would have us build entire homes out of cardboard if they could pull it off 😅
Silly question though - is there such a thing as water/fire-resistant cardboard?
You could try using some water-proof spray. I know there's also fire-proof sprays and paints, but not sure if it makes sense. At certain temperature it will burn anyway

I know they make cardboard that is waxed, not 100% waterproof, but better than normal cardboard.
