Yet another easy printable and usable mask. (Add readme.txt and zipper edition)
Why
...显示更多 will I not design this mask for printing in PLA or PETG?!
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.
That is why I don't want to convert this design to use PLA/PETG. It is for your safety.
Print and use it at your own risk.
Uses up to 10mm thickness Filter. Mask weight 23gram.
HEPA filter mount STL and customizable scad here. (See animation below)
I made this for the community, for the time being the shortage of surgical mask, due to the outbreak of the Covid-19 virus.
This Simply Version is very good looking but your lips will always kissing the mask inside. Personally I prefer the ROUND VERSION Flexible Mask Valvy for better internal clearance.

Filter
Bascially accept all kinds of filter with options cartridge at the end of this readme.
Filament
Only Nose Clamp require PLA/PETG or any hard filament. (Bend to fit your nose by hairdryer.)
All STL require Flexible Filament such as TPU
Notes:
-Use any filter you trust. Personally I use 6ply of 3M Filtrete™ (Air Cleaning Filter - Ultra Allergen Reduction)
-May try odourless anti-bacterial wet wipes as filter. (dry. dehydrated before cut & use)
-Use a hair dryer to change the sizing slightly. Annealing can sink the size of cap a little bit. (that is the beauty of flexible material.)
FAQ and Tips:
-Level the bed well. Avoid elephant foot or you won't get the needle holes.
-Avoid moisturized filament which result in porous structure.
-Trim or heatgun the mask for fitting.
-Use multi strand thread to fill the needle holes.
