HEPA Filter Montana Mask
Description
This is a re-mix of Idabkey's COVID-19 Montana Mask: https://www.thingiverse.com/thing:4239236, for some reason Thingiverse wasn't finding the original when I tried using their re-mix box above. I printed this on my Ender 3. See settings below. You will need some kind of elastic strip/rubber band to hold it on your face. I used 8" rubber bands cut and tied into the holes. This uses the popular iRobot Roomba 700 Series HEPA Filter. Version 2 had a bit of a gap in it where the filter clips into the mask. That's why I used a piece of foam mounting tape to cover up the area inside. Version 3 (this iteration) should be tighter in that area. Still, it might be a good idea to try to use some rubber cement and the foam mounting tape to ensure a good seal around the Roomba filter. One problem I have had with it is that people can't really understand me when I talk to them as I am shopping. Literally had someone tell me frankly, "I can't hear you through that thing." It will need supports touching the build plate. As with most items you will find in this area, use at your own risk. While the HEPA filter may be better filtration than say a plain cloth mask/bandana, I cannot guarantee 100% that this will protect you. I have included the FreeCAD file in case you would like to customize it further. Thanks, and stay safe.
