The materials you need for the toolbox are just scraps of plywood. Use three quarter or about 2 cm thick plywood for the bottom and the sides. only because that makes it easier to screw the sides on. The width of the bottom is 5 inch, or about 12 centimeter, the length is about 12 inch or 35 centimeter, but you can use any size as long as you make the other parts fit the bottom.
The side pieces are the same width as the bottom, and about 7 inches high, or about 15 cm. You can saw the corners at the top off to make the top part slanted inwards, it looks nice. BUT, you can also leave the sides rectangular, that is easier. Drill two small holes in the bottom just half the thickness of the bottom up from the edge. Also drill a larger hole so you can later put a rope through it for the handle.
If you need help with this part go to a carpenter’s shop, or a cabinet maker’s shop they will help you if you ask in a friendly manner and tell them what it will be used for. They might even make one for themselves, this toolbox is really handy not only to hold tools, but all kinds of small items!
The long sides are two rectangular pieces of thinner plywood, to be nailded onto the bottom and the sides. The height is 4 inch or 10 cm and the length should be the length of the bottom PLUS the thickness of each side!
Of course there is the coloured electrical tape that we use so much for decoration, and a piece of rope. We have used braded nylon or polyester, but really any type of rope will do. The length of the rope needs to be longer for the knots! You could also use a piece of wooden dowel as the handle. If you do, you should of course drill the hole the same diameter at the dowel.
