On Thingiverse, there are a large number of practical 3D models that can effectively solve the problem of hard-to-squeeze toothpaste in toothpaste tubes. This design is more concise than all the solutions I've seen. It can be easily printed with any 3D printer, and it's very convenient to clean up afterwards. It's simple and efficient to use, with excellent results. Its appearance is clean and tidy, and it doesn't look out of place at all.

1. First, print out the toothpaste dispenser. Conduct post-processing and polishing as needed

2. Gently flatten the end of the toothpaste tube, then insert the tube opening into the elongated slot of the toothpaste dispenser. Depending on the specific size of the toothpaste tube, you may need to adjust its position and twist it slightly to ensure it fits smoothly.

3. Pull the toothpaste dispenser as far as possible towards the full end of the toothpaste tube. As the toothpaste is gradually squeezed out, you can adjust the position of the toothpaste dispenser as needed and continue to push it until all the toothpaste in the tube is used up.
