Remixed from a scan of a raven skull to be a wearable mask with an articulated jaw. Source file can be downloaded here: https://www.thingiverse.com/thing:2484293

Files are sliced to fit a 300x300x400mm print bed. The model comes sliced for easier printing, I added in alignment slots and pegs for easier assembly post-printing. The orbital rings can be installed after printing once a mesh material is placed over the eyes.

Model is already scaled to fit an average adult head, feel free to scale it to your own comfort!
