1 Gallon Carboy Stopper Lock

thingiverse

My standard 1-gallon carboy had a nasty habit of pushing the rubber stopper out during long or very aggressive brewing cycles. This fix was quickly designed to prevent this from happening. The lock slides on and off the carboy at any time and allows enough space for both a blow-out line and a standard airlock to be attached. As the lock never touches your brew, sanitation is not required, though it's always recommended. The print has been oriented for maximum strength. Unfortunately, this orientation requires the most supports. Based on the forces being applied to the lock, the orientation puts the greatest stresses parallel to the print lines, making it stronger. The forces that can't be removed are oriented so the strongest parts of the print act against them.
