This mask consists of 3 parts, after printing, you can connect them to any fasteners by making holes for them. As planned, the inside of the mask should be covered with a black cloth. So when you open, your face is not visible and a feeling of darkness behind the mask was created. Also, to avoid errors when printing eyes, they are left without holes. I attach the ZBrush Tool (.ZTL) to edit the size and proportions of the face, if you need it.
