This is a Bald Eagle Bottle Opener which looks really nice.
For the long-term usage of this device there must be a thin layer of hard material (e.g. Aluminum) to cover the top part of the eagles beak.
Other then that this should work and I hope it inspires you for doing other projects.
First of all I suggest printing this thing with PLA for the right amount of durability and the main important print settings are:
Infill Density: 0.2
You should try to maybe cover the used area of the upper part of the eagles beak.
If all this has been done you should be good to go and open a bottle. :)
