Thingiverse was fun! 2021 Feb 3rd updated version https://www.thingiverse.com/thing:4748934 This is to protect others while using 3M mask. May work with other version of similar 3M masks. Also has a cover to direct out going air downwards instead of straight forward. Please visit my website for more related material and just more. http://gallaghersart.com/page/airtight_adapters_for_medical_masks_and_face_respirators Includes template to cut filters to size. Two version of the clip-on filter, 2mm gap and 0.5 gap depending on filter type used. The 2mm is for cloth cut from clean fabric – should be about 4-5mm uncompressed and @ 2mm when compressed. Fabrics vary so test before use. The 0.5 gap is for cut up filters. I used a 3M filter meant for house air filters. They are made with basically hot glue. Taking your time to be careful it is possible to remove all material from filters. I was surprised how much I could get. They are denser than the disposable masks. I may need to make a larger valve for a larger liter size. ((After testing these filters are much denser and require more area to work with, making new larger mount to use these filters, coming soon.) The clip should snap with out much pressure, when removing pry from clip area next to mask. May want to test this before use so you can see how it clicks in place before using any filters. Also, may want to print extra of this part for once it breaks. I have taken mine off and on many times with and without filters, still good. Category: Household
