The wolf mask was originally designed in 2015 and, then redesigned and reprinted in 2017 for mold making. The full 2017 mask was actually never assembled, and the mixed version is what the molded masks today are based on (2015_upper_original and 2017_lower).
In 2018 Kathryn Harris also heavily modified the molded mask to a more cut out top - this version has also been added as an alternative 3D file (2015_upper_cut).
The 3d files have been modified so that any top fits with any bottom!
