My household uses those floss and toothpick combined things, but I can never seem to find them when I need one.

I used TinkerCan to whip up a quick model that will keep a few handy when I need them.  There's a small channel at the base to prevent it from holding water because the last thing anyone wants to do is shove a piece of a mouldy pick into their mouth.
