The advantage of this mask is that, when placed on the face, the filter points downwards, reducing the risk of receiving any micro-droplets with allergens.
The mask is molded to the face and assembled with 3 pieces:
"cover" that will support the filter and attach to the mask
"grid" prevents the filter from getting into the mask
In addition to the parts, a filter must be cut out of the most appropriate fabric for each use.
The "grid" piece can serve as a template for cutting.
Once mounted, two rubber bands are required to hold it to the face.
Printed with PLA "LEON-3D blue" (I've tried better), with parameters:
195º print, 60º bed
Layer height 0.25mm
Time 4h38' + 48' +12'
For the mask, the original plane would be the connection to the lid. In this way, the material lost in flown supports is very little
