Stop throwing your Rub 'n Buff tubes in a drawer, this handy holder mounts to the wall with two screws and will hold up to 15 tubes, each is clearly visible due to the staggering.

It will print with no supports but the under side is a bit messy(when will you ever look at the bottom though?) If you choose to use supports, I'd suggest a few front to back paint on supports and at each side.
