I got my orange tool chest a few years ago from Harbor Freight but I only recently learned they make accessories for it. Shown here: A magnetic tray, a magnetic paper towel holder, and a magnetic power strip, and on the other side, a fold-out table and a magnetic hook.
I don’t know why these make me so happy–maybe it’s the idea of Harbor Freight saying, “You know, manly toolbox-owning men really DO want to color-coordinate their manly toolboxes.” I guess the urge to optimize/organize is genderless.
