About this 3D model
Both the standard Yiga mask and Master Kohga's mask, with a slightly modified design to make vision possible, as I have not yet learned the art of seeing through solid objects. Masks are scaled to be 23 cm from the top of the head to the chin, and scaling shouldn't be too much of an issue if needed. Parts for the standard mask beginwith Yiga_G_. You will need one of each. Parts for Master Kohga begin with Yiga_M_.
