Yet another easy printable and usable mask.

===================================================== (---- Notice ----)

<H3> Why will I not design this mask for printing in PLA or PETG?!</H3>

I get quite a few requests to convert this design for printing in PLA or PETG. Sorry, but I am not going to do that, and this is why: In my experience, PLA and PETG are TOO DANGEROUS to put on your face. If a PLA or PETG mask cracks, especially when printed as a light weight/thin wall, it will cut your face like a knife. It may not be happen on the first day, but it will happen one day, maybe while you are talking, and it will be sudden. Thin walled PLA and PETG will fatigue much faster than TPU, being washed, dragged and pulled in daily use. Maybe something hits your mask while you are wearing it, and it splits or shatters.

Let's see poor Kevin in the following videos: For Part 1 in PLA please go here: https://youtu.be/ErP28uP4mVI For Part 2 in PLA please go here: https://youtu.be/LlN01EW9ORI For Part 3 in ABS please go here : https://youtu.be/feWsPd2XUFU For Part 4 in PET-G please go here : https://youtu.be/k-KhRx73NxU

That is why I don't want to convert this design to use PLA/PETG. It is for your safety.

===================================================== (--- DISCLAIMER ---) Print and use it at your own risk.

Uses up to 2mm thickness Ply Filter. Mask weight 21gram.

I made this for the community, for the time being the shortage of surgical mask, due to the outbreak of the Covid-19 virus.

Good Luck everyone and my loves.
