Fully parametric cap for squeeze or pour bottles

I designed these for 250ml and 125ml soft (HDPE or PETE) liquid bottles. The ones for e-liquid usually come with a twist-top cap that has a lot of backflow and leaks all over the place. Their tip is also extremely wide, so 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 (Sm) * Spout height (Sh) * Spout thickness at base (St) * Spout thickness at top (Sp) * Height of thread start (Ti) * Thread turns (Tt) * Thread pitch (Tp) * Thread height, the difference between Dmaj and Dmin (Th) * Thread thickness (width of ridge) (Tw) **IMPORTANT**: If you are using these for anything that goes inside your body, use food-safe filaments and common sense. # To-do I'm having trouble getting the ends of the threads to end smoothly. If you're an OpenSCAD guru, please take a look at the code. I'd love to learn a new trick or two.
