About this generator
Flat in the drawer, a box when you need it. It also prints faster and with less warping than an upright box.
How to use
- Set the inside size and the height.
- Print it flat.
- Fold the long walls up, then the short walls, and push their tabs through the slots until they click.
Printing tips
- PETG or PP. PLA hinges snap after a few folds.
- Set the hinge thickness to a whole number of layers: 0.4 or 0.6 mm at 0.2 mm layers.
- The flat sheet is the box size plus twice the height in each direction: check it against your bed.
- Fold each hinge once while the print is still slightly warm for a cleaner crease.

Frequently asked questions
How often can I fold it?
In PETG, dozens of times. In PP, practically for ever. In PLA, a handful of times at best.
Does it hold without glue?
Yes. Each corner is locked by a split tab with barbs. Squeeze the two prongs together to release it.
