The following model is not an original idea, and is a clone of an extinct product no longer being produced.
This hummingbird feeder uses an upside down glass bottle full of nectar as a reservoir.
It's best to print the “Bottom Plate” in the lowest resolution possible, as printing in a higher resolution introduces more “nooks & crannies” that bacteria can hide in.
Due to the nature of the part PETG/ABS is suggested with a post processing annealing treatment.
Do not scrub these parts with a rough scouring pad as it can potentially introduce plastic particulates into the hummingbird nectar.
The author marked this model as their own original creation.
