Hummingbird feeder with wine bottle and bowden tube

We made a hummingbird feeder from a wine bottle, a plastic (bowden) tube (4mm OD, 2mm ID). The hanger is 68mm ID for a 73mm bottle. Scale it for your bottle. Both must be printed in flexible filament. The flower tip is 3.6mm ID for a snug fit around the 4mm tube. Fusion 360 files included.
