Full Facemask w/ Articulating Filters

thingiverse

This was my first foray into printing a particle mask. I wanted to convert something that already served as a mask, so I came across this mask from Amazon. It was perfect! Not only was it a full face mask with separate breathing space from the eyes (no fog), but it also kept in/out breath-ways distinct. What made this mask ready to wear as a particle mask was its breath-out valve in the front, similar to gas masks, so the filters didn't have to do double duty. My first attempt at an adapter involved using clips to keep it attached, but I found that a) they kept breaking and b) I didn't need them. These adapters fit snugly, ensuring an airtight seal and making them darn near impossible to remove. (I still have the clip design if anyone wants to tinker with them - perhaps an ABS print would be more forgiving.) I had my mask and adapters but lacked filters. I planned on using a 3M filter from the hardware store, but alas, none were available. That's when I came across Maxdarkdog's filter alternatives. His 3M adapters, great design, and use of cotton rounds I already had made it a win-win-win. The filters fit onto the adapters very tightly, with no need for a gasket. What's great is that you can position the filters front, up, down, back, or any way you please. Perhaps facing them back might keep them better protected. The project turned out better than I had hoped. The mask is airtight, adapters work great with the filters (I hope they work well with 3M filters when I can get my hands on some), protect the eyes, and aren't uncomfortable to wear - as long as it's not all day.
