I was looking at my latest playing with cardboard and trying the usual fingered boxes and not liking the results as cardboard is a bit delicate for using a hammer to push it together. Then I remembered that Inkscape made foldable boxes! So I tried one and discovered that what it made was a series of basically rectangles, with a few chamfers which would print fine but not with a Glowforge. So I put in way too much work and scaled it down and down till one was able to print on the bed of a Gowforge, where it was a bit small for most things so I am putting it up here.
The blue is cutlines and the red a blurry score to let it bend in the right places. It is approximately 3x3x2
I scooched some stuff about a bit and left two of the tabs only partially cut so you can do bigger than will fit but you need to leave overlap and cut with scissors.
