Parametric Bottle Cap with Customisable Pourer

A parametric bottle cap generator with option to include a customisable spout/pourer.I love Steve's Parametric Bottle Cap / Jar Lid and I'd been generating caps and manually adding spouts to meet my requirements. I've become familiar enough with OpenSCAD now to tweak the OpenSCAD script to make things easier for future me.Changes include the ability to:Cut the preview in half for visibility while designingSet top or bottom of the lid to measure the thread fromAdd a customisable sealing ring inside the cap (like the ring in PCO caps)Add a customisable pourer/spout, breather hole, cap for the spoutI've included some example .stl pourers and some example parameters in the .json file.Default parameters are for a PCO 1810 cap with a pourer and cap, with quality set to preview and the preview cut turned on. Remember to turn the cut off and the quality up when rendering for print.
