There are lots of Thingiverse objects to help with the problem of getting all the toothpaste out of a tube. This design is simpler than anything I have seen. It should print easily on any printer, cleans up readily, and works simply and well. The design is clean and unobtrusive.
Print the squeezer. Clean up and sand as needed (very easy on this simple, flat object).
Flatten the end of the toothpaste tube a bit, then stick the end through the narrow slot in the squeezer. This may take a bit of wiggling depending on the tube.
- Pull the squeezer towards the full end of the tube as far as possible. Continue to advance the squeezer over time as you empty the tube, ensuring that all the contents are used.
