Mask for 3D printing, passed all the autotests
Inner filter space is 52x52mm, and various thickness 6mm, 4mm, 1.5mm (also I can do for you any thickness, just write in comments)
Two different types of filter (slim and Max)
As a filter, you can use the material to your taste
Depending on the material which you choose for, you can change the scale of the lower part of the mask, if it is not flexible enough, in the original gap is about 0.6 mm on each side
The author does not claim that this mask is a panacea for all known viruses, but I think it is better than nothing
The mask has an ergonomic shape for most face types
I can’t say anything exactly about the protection against the coronavirus, I think it all depends on the type of filter that you choose as the material
on a 1: 1 scale should suit almost everyone, the cord is not included in the 3D print asset, because it must be either rubber or other improvised means
I hope you like it
