Closed Square Origami Box, designer unknown

Some readers are interested in origami that they can actually make themselves.  The trouble with that is that many of the designs are quite complicated, or it’s difficult to get instructions that can be shared.  For original designs, it can take hours to draw diagrams even for relatively simple designs–and most of them are not very simple at all.  Other designs I get from books, and the diagrams are under copyright!  And for many designs, the only available instructions are the crease patterns.

Today I present a design that I happen to have diagrams for.  This closed square origami box is not my design, but I couldn’t find diagrams so I drew up some myself.  Someone also made a video.  Diagrams below the cut.
