This is an AI designed scientifically based funnel design with natural tendency to create a vortex in the liquid. The vortex naturally leaves a central air cavity for air outflow. 

The smooth shapes curves ensure laminar flow under all circumstances. 

Even if you fill the funnel and close the air cavity (not that easy), the spiral channels are mirrored on the outer layer leaving air channels between the funnel an the bottle neck allowing the air escape there and quickly restore the inner air cavity.

This design fills the bottle in roughly half the time compared to regular (Ikea) funnel.

The model comes in 3 sizes optimized for 0.7l glass bottles (for wine), PET bottles and the largest I use for wooden barrels in my winery).

Use transparent PETG for food and drinks.

Prints perfectly fine without supports while standing on the narrow end (like a mushroom), but use a rim. 

Models are optimized for the northern hemisphere, I can produce AU version on request.
