Filter Face mask

I altered the dimensions of the filter holder to better optimize the material I am using as well as the way the material is held. I am using a MERV-16 rated filter which has 6" pleats. I made the filters 3" to get two rows per pleat. By making the grill on the mask slightly smaller, it pinches the material over the edges. I also added a step inside the grill so the filter material is pressed backward as well as pinched on the side. I felt I could assemble the masks much faster this way rather than gluing in the filter material. The cover is the same for both mask sizes.

Edits: Added second pair of mounts. Opened mount holes larger. Better aligned mounts for better printing. Revamped transition from base grill to face piece reducing filament and weight. Thickened face piece wall slightly and made more consistent for better print quality.

All the same dis-claimers of the original design apply.
