Another bottle bird feeder

20190222 Added funnel to help fill the bottle with feed.

Inspired by this https://www.thingiverse.com/thing:251085 and others I decided to make a roof. When it rains the water ran down the bottle and into the feed. You may put some silicone between the bottle and the roof to make it water tight.
Being at it I made a reinforced copy of the automatic feeder.

I added mounting rings at the feeder and the roof. Make a net around the bottle like a fishing net. See picture.

If you use the openscad app to redesign the feeder you have to include this https://www.thingiverse.com/thing:8796 into the same folder.
