Sometimes you have enough toothpaste in the big tube, but not enough in the small tube. Solved.

Sometimes you have a few small tubes that are almost empty. Consolidated. 

Sometimes you just want to connect two tubes together and squish some toothpaste back and forth instead of finishing your packing. Enjoy.

This is a simple print to solve a simple “problem.” But just to keep things interesting, Crest and Colgate use different sized caps. So there is a Crest size, a Colgate size, and… a Crest-to-Colgate size (0 of 5 dentists recommend).

If you use another brand, you remain trapped in a world of half-empty travel tubes and wasteful purchases! Or you can remix this by adjusting the scale and tell all your friends you invented the world's first Arm & Hammer-to-Sensodyne conversion protocol. Go for it Tom, of Maine.
