6800 Exhaust Filter

This was modified from 3M 6800 full face respirator filter cover
by limhueysing. I found the original filter to be too small, so I made it larger.

I printed it on a Prusa Mini using hatchbox PLA. I then cut out a circle of surgical mask and inserted it into the filter. It works very well.

I am not an engineer, so use this thing at your own risk.
