Work the box a few times before you go on to make sure it flattens. Then glue on the printed panels. The tall ones go in the back. The larger panels go on the bottom sections and the smaller ones go on the box flaps.
Attaching the Tools
Now for the wires. The only way to get the wires to stay is with a glue gun. First, cut a piece of wire about 6 inches long. Then wrap the wire around a small cylinder. I used a crochet hook but you can use anything. Leave about a half inch on each end un wound. Glue, with the glue gun, one end to the tool and the other end to the box slats (orange pieces in pic above). Make sure to attach them randomly.
