Autorefill bird feeder for mounting on a 38 mm diameter PET bottle (Cappy, milk etc.).
The bottles with a suitable thread can be found with a capacity of up to 5 liters (1 gal)
This variant is specially adapted for larger birds like spotted woodpeckers who cannot sit comfortably on the original feeder. Of course, fully satisfies even smaller birds.
Good results for PET and PLA, for quick printing I recommend 0.30 mm layer (about 3:20 on i3 MK3).
