mask against covid 19 flexible 3D 打印模型

mask protection against the covid 19 fully printed, which has the follo***g advantages:

-make a perfect seal adapting to the face, envitating the air in.

-avoid odors due to sweat, as it is easy to wash and the material does not absorb moisture

-it's very ergonomic, as it fits the face and you can use it on your ears or neck

-it has two threaded air in inputs, in which filters made of face cleaning cloths are housed, which are interchangeable for greater practicality and cleaning.

-it has a deformable nose clip in hot water (80 c), made in pla, which achieves an ideal adaptation, to avoid fogging in the glasses.

-easy to elaborate

-if you like my work, i appreciate your support =)
