Wine Stopper Options

I made the cut version to fit onto a metal stopper I already had. Obviously, an air gaps are a less ideal storage solution. And … it's all a basic concept for short storage … not an airtight solution for keeping fine vintages :).I printed the gaskets in TPU 95A, 0.20mm layers, 2 walls, 5% gyroid infill. I think flex 85 with another wall might be a better option but I don't have any on hand at the moment. This works.
