This is an extra large funnel that we use to fill mason jars with food from our freeze dryer trays.  It fits both small mouth (58 mm) and large mouth mason jars (74 mm).

The pictures are of the first prototype.  The version here is the latest one with a couple of tweaks to make it print better and fit the jars a bit more securely.

I printed this at .3mm layer height and 4 perimeters using Prusa Slicer.  This gave me the fastest print time and is of acceptable quality.
