Toothpaste squeezer with redesigned locking mechanism. There are two sizes for 54mm and 64mm wide toothpaste tubes. Also, I added a 64mm handle with a 0.5mm slot for the toothpaste tube. Original handles have a 1mm opening.
Added base with 1mm gap on top. The original base has a 0.5mm gap.

The locking gear should have a loose fit on the handle shaft. And should stay inside the base when the handle with the old tube is pulled out of the base.
