breathable filter lid Kombucha

thingiverse

I started brewing kombucha but wasn't happy with just a towel on the top. Once a fly managed to get in the jar so I decided to print a better solution . as filter you can use a makeup pad or any other breathable material. it gets screwed into to lid. also you can use the lid when you want to remove liquid from the jar without getting big pieces like the Scobi out.
