P100 Filter Cover

This is a total redesign from the source. In this design I make the cover hold on to the filter connector, instead of the filter itself. This way we can have more space around the filter while the cover can hold firmly onto the mask. This print can be quite non-porous at 1.6 mm wall thickness by using extruder multiplie of 1.1 or 1.15.

With this cover, the users can repeatedly using the P100 filter for a few days while disinfecting the cover using alcohol, hydrogen peroxide, or other cleaners. From testing the filter does not interfere much with breathing while adding minimal extra weight to the mask. The added red cross logo helps identify this as medical device.
