I noticed recently that the original model has disappeared from Printables and yet a fair amount of people I've seen online wanted to make this themselves. Made a couple of these masks myself and I love them.
Unfortunately, I don't have all the models saved, but I do have some pre-sliced files. I only have the gcode files for the fangs, so hopefully you can either use them as they are or remodel them yourself.
The user re-uploaded this model. The user is not the original author of the model.
