Filter Grill Modification for Bolivair Style COVID Mask

I print the masks with flexible style filaments for better sealing and comfort. The original style with the flex filament can cause the "grill" to pop out. This adds pressure to the retention points.

Credit to the original, it is a very nice design: https://www.thingiverse.com/thing:4244081
