Thing3

This thing can probably be used as a toothbrush holder. The four holes might be a little small for some toothbrushes, but you could use the larger center hole. Or try the included large version.

It also makes a decent base for Thing2. If you flip it upside-down, it can be a cool looking base/support for something, like a glass of water.
