Face comes out best when printed beak pointed up, though that does require a lot more supports. So make sure to support the tail from the front and the back so that it doesn't fall over mid print.
The author remixed this model.
Upgraded model
v2
Rounded eyes
Thin feet
Clean attachment of beak and eyes
v3
Leveled feet
Pitched up tail (because that's how duck tails are)
v4
Carved out fingers a bit more for realism
By request: Added fingernails to back fingers. (Someone wanted to paint them ¯\_(ツ)_/¯ )
3mf file was made with Bambu Studio and it comes out as good as I care to make it.
