This is a remix of https://www.thingiverse.com/thing:2413802 I've turned it around, making it simpler to print and adding extra strength to the design. It's super handy to attach this to your beer or soda bottle, ensuring no pesky insects can get inside. For optimal results, I recommend printing with TPU.
