The real blank at this size, folded by the same engine as the studio. The artwork is a sample from a fictional brand — swap in your own in the editor.
File-bottom box dieline
Regular slotted flaps on top and a double file bottom: a floor whose wings fold up inside the end walls and an outer flap under it — a square, reinforced base for files, documents and heavy stock. A parametric template — change the length, width and height and every panel, tuck and glue flap is redrawn to match.
