Create your own articulated frightening mask. You just have to print two parts and fit the axis of the jaw. Then, add a thin elastic cord to open and close the jaw.
the print came out without an issue would be 4 out of 5. the print didn’t count as successful since my AMS jammed after it was printed so won’t allow me to give 4 stars. it puts a bit of pressure on the bridge of my nose. if I was to print again would probably scale up.
