Quality is VERY good, however as like any product with the advertisement/allure of being 3D-printable, an instruction set, print settings, filament type, and overall finished build/proof-of-concept print would be appreciated. I'll try printing and follow-up my review.
I think this is reasonably priced overall, despite the lack of instructions. If you're looking for a one-stop product for the mask, this is as close as you're gonna get I feel.
Learning/experimenting is half the adventure!
-edit-
On further inspection, it appears the mask is too large, needing additional work to separate. There area also minor details like the wiring on the left (wearer's right) temple/skull portion of the mask looking difficult to print. I wish these details were further separated or have the option to print without.
