Funnel with air ducts V2

This is an Improved version of the previous design I uploaded.

This is a funnel with some features I think help do its job better. The first being a longer nozzle, while this does not help to funnel the water it helps the funnel stay in the throat of the bottle and help keep it from falling, freeing both hands. The more notable feature are the air ducts that run along the side all the way to the top of the funnel. This helps air from inside the bottle escape by preventing the funnel form a seal with the throat of the bottle (or whatever the receptacle is). No matter how deep the funnel sits, there will never be a seal that prevents the liquid from flowing in at the fastest speed. This new version has wider ducts that allows more air to pass through and is overall much thinner with less wasted material. With it much thinner it is not as strong as the previous but it should still be good. (Let me know if it breaks and I might try to make a version that is more rugged).

Credit to Bjarne Zeb Jørgensen (https://www.thingiverse.com/zebski/) for the great idea of making the ducts wider.
