Squirrel Proof Bird Feeder
cults3d
I don't know if this works or not, my wife won't let me put it up to find out, so I'm hoping you will test it for me. You will need a standard 608 bearing and a 3mm screw and washer to complete assembly. The idea is for the squirrel not to be unable to stay on since the fixture rotates on the bearing, but a bird would have a stable platform. The cup is removable for refilling. Fill cup on one side with peanut butter mixed with sunflower seeds so that the weight of the cup keeps the holder balanced.
