Primary Colors Box: 199? - Gilman School
I did this one in middle school as well. I was thinking a lot about boxes and how they work, and wanted to make something different. The yellow pin on top locks it all together, and when removed the two right angle sides with the squiggly break between them can hinge open. I had some trouble building it, as I was inexperienced in making precision pivot points and angles, but it eventually came out ok.
