Optimized Toothpaste squeezer

I used multiple versions of toothpaste squeezers and I have found that there are aspects that I like about each one. I enjoy a highly optimized squeeze because I don't like waste. I like the simplicity of the split shaft, and I like the petal key for holding the position you want.

Let me know what you think. Thanks!

Supports needed like the Cura image attached / like the 3mf example slice.
