Don't want to describe because it will be suspended soon again :)
WARNING: Check the dimensions before the printing! Because for somebody it can be a bit small or a bit large. And because PLA (and other type of plastic) can shrink and deform a little after printing. For example when I've checked how this mask fits in the first month after printing on my face and on the faces of my friends it were OK, but after about 4-6 months it became a bit small for me.
