This model is made for wearing. The Jawline is rounded to sit around your neckline, and the eyes can fit mesh and glue on top to see through.
For the Jaw you can use velcro straps to secure it to your neck and when you move your head up and down it will look like the Freddy Fazbear head is opening and closing his mouth. The eyes fit snugly into the mask, but I did not include eye lids but you could paint them on the mesh eyes. FYI, I did not print this yet but you guys can tell me how the print went.
