High Flow Funnel

I needed a funnel to make taking water to our chickens a bit quicker and to keep the water from spilling everywhere. The fill port on their waterer is about 1" and it was taking a long time to slowly pour the water from a pitcher into that small of an opening. I also added an air channel on the side so that as it fills up, there isn't any glugging and the water goes in quickly. I mostly designed this to work on my CAD designing ability as well as making a practical item that would be useful.
