Funnel - wine bottle neck size

thingiverse

Funnel designed to fit in the neck of a wine bottle Obviously with 3D printed objects, consider food safety and water-tightness. This will do for a temporary stop gap solution Approximate diameter of the narrow end of the spout is 12mm increasing to 15mm where it meets the main body of the funnel. Can be resized up in the slicer as necessary but not too much smaller or the walls will get too thin
