LID TO FERMENT IN KORKEN JARS

thingiverse

Lids with Siphon System Replace Ikea Korken Bottle Lids. Two Models Prevent Air from Entering Bottle, Allow CO2 to Escape. Perfect for Preparing Sauerkraut and Other Vegetable Fermentations in Complete Anaerobic Environment. During Fermentation Process, Fill Lid Hole with Water Every Two or Three Days Depending on Heat of Location. Second Model, "New Cover," Requires Only Printing; No Additional Action Necessary. First Model Requires Inserting 4 mm PTFE Tube into Lid and Attaching It. I Used Polyurethane Resin for This Purpose.
