Throw Out That Box? No, Build a Shelving Unit [Hackaday]

View Article on Hackaday

Are you one of those people who hoards cardboard for someday, and then periodically breaks it all down and puts it out for recycling because you haven’t done anything with it yet? Well, load up a new blade in the utility knife and fire up that hot glue gun, because the [Cardboard Ninja]’s gonna show you how to make a shelving unit from the biggest box in your collection.

[Cardboard Ninja] goes about the build quite smartly, cutting the legs from the four long bends already in the cardboard. This is repeated in the shelves, which are made from the box’s sides — [Cardboard Ninja] takes advantage of the bends when it comes to cutting out the shelves and creates the other three with the edge of a metal ruler. The rest of the cardboard is devoted to supports for shelves and legs.

While you could use this unit to hold all the other, smaller boxen you have lying around, that would be a gross under-utilization. You see, the way this is put together, it can hold upwards of 133 lbs (60 kg) total, provided the rules of weight distribution are followed, and the heaviest things are on the bottom shelf.

That does seem like a lot of weight, but given that this was constructed by someone who has a holster for their utility knife and calls themselves [Cardboard Ninja], I think we can trust their stress tests and just go with it. Given that, it’s always a good idea to anchor shelving units to the wall.

You know, this would make a pretty good entry into the second Challenge of this year’s Hackaday Prize. Remember: this is the final weekend to enter, and the window closes at 7AM Pacific on Sunday, so get hackin’!
