Pocket Laser Engraver (structure)

A friend at our makerspace made a little engraver with some dvd burners, following this Instructable http://www.instructables.com/id/Pocket-laser-engraver/ (working surface : a bit more than a business card)

But I wanted to give it a nice structure (and maybe an enclosure later), this first version is even foldable :)
