2 liter bottle neck finish model

As an exercise in mastering Fusion 360, I've created this bottle neck that meets the PCO-1881 standard, widely used in modern 2L bottles. If you're only interested in interfacing with bottles, I recommend using Laird's model. Instructions: I'm puzzled as to why anyone would want to print this design, but if you're determined to do so, the best approach is to print it in two halves horizontally and bond them together. Printing in one piece may be challenging due to the overhangs. You will need support for the interior arch. I haven't provided a split model, but most 3D printers allow you to perform a quick and dirty split by duplicating the model, rotating one copy, and positioning both below the print bed so that the bed is at your desired parting line. Place the parting line perpendicular to the thread start.
