I decided to make a deck box that was compatible with another tool bin storage brand, so here it is. Unfortunately, the inside of the Kobalt bin has some weird shapes to it that are not exactly consistent with the others, so I've included my first pass on the central pieces. As usual, it's just out here in case anyone else finds it useful. Feel free to make suggestions on this one or design your own based on what I've done, I won't mind :-D
