Cardboard box close clip

SummaryThis may seem like almost a no design because of its simplicity, but it is fully functional. I re-use the cardboard packaging boxes that come with the many things I order online. They're usually quite strong and are ideal for keeping stuff like pencils, craft hand-tools, and other small stuff. But as I access the contents frequently, I don't want to have to seal the box every time, to avoid the flaps from remaining open. So I have created this closure clip which slides in between the two longest flaps and holds the box closed without sealing it. The bigger or longer the box, the more clips can be used.InstructionsThe 4mm clip will accept up to 3,5mm thick card and the 7mm clip will accept up to 6.5mm thick card. Just print it and then slide into position. I recommend using at least two clips to close the box.
