Fully parametric cap for squeeze or pour bottles

I made these for 250ml and 125ml soft (HDPE or PETE) liquid bottles. The ones for e-liquid normally come with a twist-top cap that has a lot of backflow and leaks all over the place. Their tip is also extremely wide and I wanted something thinner.

This fixes both issues and after modeling it in OpenSCAD I made it fully parametric. You can adjust:

* Cap internal diameter (Cd)
* Cap internal height (depth) (Ch)
* Cap wall thickness (Ct)
* Spout major diameter (Sd)
* Spout minor diameter
