3D model description
I made this Mask for my wife as she is an essential worker. This was an update on the Covid-19 Mask V2. I changed out the filter to this 2 part holder. It holds the "filter element" in place firmly so there is no risk of it shifting when assembling. The 2 parts actually use less material and print faster than the part it replaces. We also found the air flow is slightly improved.
She also wanted this to look not like a face mask so I made a magnetic pig snout. This usually puts a smile on the faces on the people she interacts with.
The snout is held on my a 20x5x2mm magnet in the snout and a 8x3mm magnet in the spacer. I used a 3/8" x 1/2" hollow weather stripping for the seal. It makes this mask easier to wear for an extended period of time.
For the "filter" we have tried the 2 layers of blue shop towels. Their are several articles that have said that these are good for filtration. I will try shop vac filters and some other materials I can find around the house.
I am testing some other filter holders as well to provide better air flow. This mask does provide enough to breathe but if you have any difficulties breathing this may be too restrictive.
I will upload STEP files as well to allow people to modify easily.
