Carboy Bung for Blow Off Tube

thingiverse

Design a Better Bottle-style carboy that can be customized for a blow-off tube rather than an airlock, elevating the brewing experience. Edit: After printing this model, it was found to be not airtight with a 20% fill level. To achieve better results, consider printing solidly or sealing the model with a suitable sealer. Submerging in water-based polyurethane for 30 minutes and then drying it can yield satisfactory results. Alternatively, using ABS plastic may prove beneficial, as it can be sealed using acetone vapor (a process that works well).
