My hummingbird feeders were getting quite sun damaged, so I designed some replacement parts to fit the original glass bottle. The glass bottle is from the Perky-Pet 16oz hummingbird feeder, model 204CP-4, though I've included the F3D file for editing if you have a slightly different one.
I did redesign the bottom so that the flowers and spouts are much easier to print. They also have notches so they all align properly.
