v3 with bigger inlet for faster filling.
Designed to help inflate weather balloons.
This fill adaptor accepts a 20mm ID pipe on one end with a jubilee clip to secure. The balloon neck is pulled over the large end (OD 40mm), and a cable tie is tied around the notch to stop gas leaking while it is being inflated. The legs are for tying on weights.
OpenSCAD file is attached so you can modify the dimensions if you wish.
