This is a simple card container. I created 3 x of the NW_Cards one so that they could be laid in the original box.
You need three NW_Cards and one of the NW_People.
This is a quick print because I used "Vase mode" (a.k.a. "Spiralize Outer Contour") and it makes the walls just as thick as your nozzle.
