I already designed a box of sorts as one of my backlog of projects waiting for you know what. Over my lunch break I tweaked it a bit for this thread by adding the Glowforge logo and developing a rendering of it. The logo is a full cut, exposing the pattern on the tissue box behind but could easily be removed or customized to whatever someone might want.
I designed this for 1/8" material. No accommodations have been made for kerf yet as I am not sure how to deal with that until I get hands on with the Glowforge.
The box is 9.5"x5"x5" which fits the large Kleenex box and likely others too. The design could be easily modified for other shapes and sizes as well.

Edit: I just noticed that the PDF has some weird line weights. Not sure if that effects the laser cut or not but I will see what happened there when I have time again
Edit2: I think I have resolved the lineweight issues in the first PDF.
