The wife wanted an “I opened the wine, don't let stuff in” cap for her wine bottles to aid in her enjoyment of the beverage. So I came up with this.

This is meant to be printed in TPU since we need the squish for a nice tight fit - the cap is slightly larger than a default wine bottle, but goes in easy with slight pressure from the top. For the default printing profiles we are additionally adding fuzziness for a more organic look.

Notes on the models: In addition to the .stl models and the .3mf files, I'm also sharing the original .scad model file - this requires BOSL2.
