About

This free rounded box generator makes a curved-corner box using a living hinge: a single flexible wall that bends around rounded top and bottom plates. Tune the slit spacing to your material so the wall wraps smoothly, then glue the seam. Great for elegant gift boxes, trinket cases, and planters.
