One Way Fermentation Valve For Soda Bottles

cults3d

This is a valve designed specifically for fermentation, perfect for crafting your own alcohol. I created it with Mead in mind, and you can easily assemble the cap and valve using glue - 3D Gloop's PLA Glue works well, but superglue will also get the job done. Make sure to fill the valve part with water first, as it acts as a one-way check valve that allows pressurized CO2 and air from fermentation to escape while keeping lower-pressure air out of your brew. You'll also need a reliable seal for this setup. I've experimented with printed TPE/TPR seals but haven't had much success. Instead, grab a silicone seal off Amazon - it's easier to get one that seals well over time.
