foil balloon filler nozzle

Filling or stretching a foil balloon with a valve inside requires some long straw to push in behind the valve to release the pressure. Paper and plastic straws are usable but hard to adapt to either compressor or rubber nozzle on the Helium tank. This adapter fits inside the balloon through the valve and allows filling or retracting air without problems. This nozzle fits on the rubber nozzle but also fits in some of the air pumps for floating toys, boats and so on. The latest stl has a minor change from the original design, I decided to add a slight taper to the tip to make insertion easier and to minimize the chance of tearing the balloon. The OpenSCAD file was generated by CoPilot and after some arguments this result came up . Rendered with OpenSCAD and imported in PruseSlicer. Average print time for one nozzle 25 minutes.
