#6: Transferring Toothpaste
This 3D printer invention defies the odds. People like to say that toothpaste can’t be put back in the tube. This is pretty much true—until now! This genius invented a connector that connects two tubes of toothpaste together. The purpose of this connector is to push toothpaste from a regular-sized tube into a travel-sized tube.
With this invention, travelers no longer have to buy new travel-sized toothpaste tubes. They can save an old tube and refill it with their favorite toothpaste. We’re sure these tubes need to be replaced over time, but overall, this idea is brilliant. All they have to worry about is making sure they don’t lose the toothpaste caps! Take that, toothpaste companies!
