Bird Feeder (Wine Bottle)

I designed this bird feeder to use a wine bottle to hold the seed. I have seen a few similar designs but none suited my needs exactly.

You will need a piece of rope roughly 3mm in diameter:

- Tie a loop in the middle of the rope to hang the feeder from.
- Leave the knot quite close to the feeder. If its too far the top print will not hold the bottle securely and the feeder can flip over.

Edit: I have had a few incidents with strong wind where the top part has lifted off the bottle, resulting in the whole feeder flipping upside down. As such I have added a new top part that is 5mm longer.

Update, Ive added a funnel to help fill the bottle.
