All models I make is made of card/paper/cardboard in different thickness varying from the 60grams copypaper via 0,2mm-0,5mm and 1mm cardboard.
The only things thats not made of paper is windows, and some internal metal rods in wheel legs,control sticks and other things that is useful not to make from paper
The mess just builds up....
I usually clean up after I have finished a model, to make a fresh start on the next
