Vacuum Wine Saver Cork Valve Adapter
thingiverse
The original model had some issues - i.e gaps in the model (see my comment on the original model). Furthermore, the dimensions didn't work for the vacuum bottle stoppers i got. So I redesigned it based on the original model. I already printed and tested this and it works fine for me. However, if you notice any problems please let me know. I used PETG but i guess PLA should work fine too. I printed this with 6 walls to make sure it is airtight. I used a flat rubber seal i created myself using TFC silicone (Type 18), but any seal with a big enough diameter should work. I attached the adapter to a bucket to be able remove air bubbles from the silicone and get better seals.
