About

Folding Box Generator designs boxes that fold up from one flat sheet and lock themselves shut, sized to whatever you want to put in them.

Pick one of twelve structures, from a mailer or a cake box to a retail tuck carton, a gable carry box or a set of slot-together dividers. Type the inside or outside size in mm or inches, add a window, a hang tab or your own logo, and watch it fold up and unfold in a live 3D preview.

Print it flat, with no supports, as a 3MF whose fold lines are grooved in.

Selling what you print

Personal use is free and fully functional. To sell prints you need a commercial licence: the membership covers this and every other generator.

Every export carries an invisible provenance mark. It does not show on the print and never locks a feature. What is this?
