A small, dependency-free web app that generates a cutting and folding dieline for a hinged-lid cardboard box.
Enter the box's inside width, length and height in millimetres. The live preview shows red cut paths and black fold/engrave paths; Download SVG saves the same full-scale vector dieline.
The dieline includes a rounded tuck-in lid, side flaps, locking corner tabs and slots, plus a close-fitting rectangular cut perimeter to keep the sheet rectangular. It does not compensate for cardboard thickness or laser kerf, so test-fold a sample before production.
