Hi guys.
It's is my first filter designed for sewing into leather or fabric mask
This filter is experimental prototype with different issues, I'm not recommend to use it.
Instead you can use [new version](https://www.thingiverse.com/thing:4289966) of filter
Second version more convenient to use and need little bit less time to print.
