Sparkling wine bottle cap

thingiverse

This clever cap lets you turn empty bottles of bubbly into reusable water containers. Tested and proven to work flawlessly with Champagne, Prosecco, Spanish Cava, and German Sekt! The cap keeps leaves, insects, and other unwanted visitors out of your water, whether you're drinking it indoors or outdoors. And since the cap stays attached to the bottle, you won't have to worry about losing it or getting it dirty from spills or dust on the table.
