Toothpaste squeezer v3

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.
