This is a super-easy box which can be cut on almost any laser engraver / cutter.

The DXF file has been formatted to fit perfectly on the 11 x 14 plastic sheets you can buy at home depot. I left the second box empty, to allow you to quickly put in a design, or text and cut. In the photo's I just typed my kids names onto each side.

I DON'T recommend using the Lexan sheets, as lexan / polycarbonate absorbs IR, and gives off a horrible noxious odor.
