PvT Phase Diagram for water (substance expanding on freezing) & pure fluids

This is a remix of the PvT diagram made by GianLlanos.
I improved/smoothened the surfaces and inspired by Natan Zawadzki's remix on GRABCAD I added the supercritical fluid region.
There are one german and one english version available. I also uploaded the stl, step and fusion 360 files. Like this it would be easy to adjust the terms.
