Airlock / Gärspund

Airlock / Gärspund

A simple small seal (tubing diameter = 10mm) with a stopper for bottles with 17mm bottle neck opening. I printed the stopper in TPE, the seal and lid in PETG. If other stopper diameters are needed, just let me know. UPDATE [27.11.2017]: The stopper can now be generated using the Customizer (default diameter = 38mm / 30mm).
