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.
Four-channel insert dieline
One connected blank rolls into four open-ended rectangular channels in a 2 × 2 block. Integral return liners glue to two joined bases; no separate dividers are needed. A parametric template — change the length, width and height and every panel, tuck and glue flap is redrawn to match.
