i used more layers than 5
i done the layers in stages and cutt it hard.
i'm not saying you couldn't do it the way you say but getting the air our of 5 or 6 layers at once is a bit tricky
getting the outside profile is easy
it's getting the foli nice and even and getting the bottom bit that fits in the box nice and square that takes a bit of time
