STEP ONE:
Decide how many tools you want your organizer to hold, and then determine the width of your charger shelf and tool holder shelf. I used three aluminum pieces to make a tool shelf, a charger shelf and a connecting back piece to be mounted to the wall. I wanted my shelf to hold six tools, so I made my charger shelf 23" long and added extra length on each end of my tool shelf so I could bend the sides up.
