The requested duck face is here!

You find 2 models here: one is for decoration the other is with holes on the bottom for being able to breathe normally in it.

The ear piece is connected with a filament hinge. Insert a 1.75 mm filament piece.

Note that because of the weight on the front and not matching your face well it can happen that it will fall off your face (like for my girlfriend) . But you can easily fix that with a rubber band behind your head which are connected to the ear pieces.

Printing: Warning! It's not a one-two hour print. 

To minimize the support: set the support overhang angle to 83°, for me this was the best. It needs just a little bit of support in the middle see on the second picture.

Also added the model components for a bit more easier scaling and remixing. Cheers!
