I used Blender to make a full face mask. I downloaded a CC0 cat and decimated its head. I edited it for minimal triangles and maximal good looks. I scaled it to my head size. When I cut the parts, the UV mapping kept the correct proportions. Then I brought it into Affinity Designer to scale it to actual size. Below is the 9 page print file. The sizing for the parts is optimized for a 8.5×11 page.
