Origami Parabolic Shape from a paper square

I've folded this shape quite a few times, inspired by the work of Eric Demaine (Check out his work, he's brilliant!), among others. Folding this from a square without any other aids than your hands is a time consuming chore. This simple DXF cuts a square from an A3 size piece of paper and dashes the folding lines, making the process considerably less time consuming and a lot easier. BEWARE: The dashes I've used may not work with your CNC laser/software setup. If it doesn't, select all the lines
