Free_mask

Since a mask was not available, I made a simple mask.
Please use it freely because it is free.

Filter:　Free_mask_fix_ring_pi64.stl
It is a fixed part. Output as a set with the main unit.
You can use many things, such as tissue and kitchen paper.
I think good it is the paper pack of the vacuum cleaner.
It is fixed inside by pushing in the filter to hold.
If the filter is thin, it's loose. I'm now, considering countermeasures.

Main body:Free_mask_taxxx.stl
Fix it:You can fix it with rubber belt (ear hanging and another)

Enjoy data:
Data 000 is the material for processing. There is no hollow in the filter section.
You can cut out your pattern. (Reference 001, 002, 003)

Many people's ideas are shared,
We hope that a lighter and easier to use mask will appear.
By all means, please upload your improved works in the comments!
