Hummingbird feeder replacement stopper

This a replacement part for a popular style of hummingbird feeder. A friend had this stopper/gasket piece break from frequent use, and asked if I could print a replacement. We own the same type of feeder, so I was able to verify the replacement works as intended. While the original was one formed piece (pictured in one of the gallery pics), the solution here is two pieces: a threaded receiver for the bottle top, and a washer-like gasket to “seal” the bottom of the feeder and protect against fluid backup and maybe ants. (Though let's be honest – ants are going to get in there if they want.) I think it works as-is but you could glue the two pieces together if you want. Printed using Bambu TPU for AMS. The flexible material helps with installation and removal during cleaning, as that washer has to snap into place within a groove in the feeder bottom.
