Simple bird feeder designed to need refilling less often and to keep birdseed protected from the rain. I recommend printing the hopper with thin walls so it can be seen more easily whether or not the feed is running out.

Hang with a single piece of string through base and roof with hopper between. I recommend you tie a small washer to the string and pull it through all 3. This allows the roof to be removed from the combined hopper and base for refilling.
