Hario V60 to Alfi Hotelo 0.6L Adapter Ring

I found the perfect thermal carafe for me in the Alfi Hotelo 0.6L. However, it didn't quite fit my Hario V60 size 02 correctly. So I printed an adapter ring. The ring sits in the carafe and the V60 sits on the ring perfectly flat. Note that this will only work with a plastic V60 - ceramic versions have a bottom too wide for this ring.

I printed my ring with 100% infill in Proto-Pasta HTPLA and heat treated it to ensure it would withstand brewing temperature without deforming. After use, I have measured the ring at about 70C to 75C with an infrared thermometer so I would suggest using something more temperature resistant than normal PLA. No coffee touches the ring so I don't personally have any reservations about food safety but it's something you should keep in mind.
