Create a 5-sided, 7-sided or even 13-sided box. The lid is separate and slightly larger, which can controlled by setting the “clearance.”
You can choose any number of sides, as long as there are between 3 and 20 sides (inclusive). 4 would be boring, though…
Boxes with 3, 4 or 6 sides assemble beautifully into larger constellations when you make a couple or more of the same.
