Wine Bottle Funnel

thingiverse

UPDATE: The original design had a tendency to seep down the side of wine bottles, which has been resolved with this new version. It's now taller and wider, allowing for more liquid to be poured without overflowing. Other refinements have also been made to enhance usability. This accidental creation was initially designed for a completely different purpose, but it surprisingly works well as a standalone funnel. The latest iteration features a recessed bottom that allows it to sit securely on standard screw-top wine bottles (or any other item that fits), eliminating the need to hold it in place. As someone who makes Kombucha using wine bottles, this design is especially convenient for me.
