The Hose Bib Bottle Filler Spout narrows the outlet to fit into bottles. It was sized to fit PET soda bottles and has an outside diameter of 20 mm. There is a vent incorporated to allow the air in the bottle to escape if the bottle is seated against the nozzle.
Printing is best with 2 walls using a 0.4 mm nozzle. No support is needed and the wide end is intended to be on the bed.
The author marked this model as their own original creation.
