Fusion360 custom thread profile for soft drinks bottles (PCO1881 spec). Unzip to \Users\"USERNAME"\AppData\Local\Autodesk\webdeploy\production\"CURRENT VERSION"\Fusion\Server\Fusion\Configuration\ThreadData
Note: You'll need to change "USERNAME" and "CURRENT VERSION" to match your own install. The current version should be the one with the latest date stamp.
V2 internal thread (the 'cap' thread) is a little tight and might need working on and off a few times, V3 is a bit looser. Neither will provide an air/watertight seal though so you'll need to model in a gasket or o-ring of some sort to stop it leaking.
This is not a perfect recreation; the official thread spec calls for a rounded thread profile and the printed thread is triangular.
Edit: If Fusion 360 updates and you no longer have the PCO threads listed in the thread tool you'll need to move them from the old location to the new one. Both folder will be in the same place; \Users\"USERNAME"\AppData\Local\Autodesk\webdeploy\production\ just look at the creation dates of the folders to find the latest and previous ones.
