175% is unlikely. If margins are proportional, width and height should increase by 41.42%, to a 141.42% total*. In practice, the printer might have set the margins to be constant (e.g., 1.5cm instead of 7%) instead of proportional, changing the fraction slightly.
I'm not sure about stuffing the model. In order to be of any substantial benefit, a weak material like TP should be packed fairly densely; wouldn't it add more weight than strength? I suspect a few cardboard strips, strategically laminated
during the build, on pieces already folded/curved, would give a better cost (=weight) / benefit (=sturdiness) ratio.
* A4 is about 210mm on the short edge, and 297 on the longer one; A3 is 297 on the
shorter edge, which is thus 297/210 - 1 = 41.4% longer. This ratio applies to all
linear measurements of the model.
BTW in a previous post I wrote "141.42% greater"; that's obviously imprecise: I meant the A3 model would be 141.42%
as large as the A4 version, therefore 41.42%
larger.
