2L Bottle Feeder for Larger Seeds

thingiverse

I created a custom version of Gazorpa's "Big Bird Bottle Feeder" using Blender. The feeder itself was enlarged to increase the size of the seed holes, while maintaining the same thread size to fit on standard 2L bottles. A short dome shape replaced the conical interior to evenly distribute seed. These two modifications enable the use of larger seeds and blends like sunflower seeds or fruit and nut pieces. I used this remix after discovering that the original feeders were clogging up with higher quality seed blends, causing issues for birds like Nuthatches, Chickadees, and Titmice that prefer these types of seeds. The updated feeder solved this problem by allowing a smoother flow of seed into the tray.
