LID TO FERMENT IN KORKEN JARS

thingiverse

Lids with siphon system to replace the lids of the Ikea KORKEN bottles. Two models that prevent air from entering the bottle and allow CO2 to escape To prepare sauerkraut and other vegetable fermentations in complete anaerobic environment The lid hole must be filled with water during the fermentation process. Controller every two or three days depending on the heat of the place. The second "New cover" model does not need any action other than printing In the first model you have to pass a 4 mm ptfe tube and attach it to the lid. I have used polyurethane resin
