MMM Respirator Filter Housing

prusaprinters

<p>I needed new filters for my 3M respirator but they have become pure unobtanium at this point so I made my own. I made these so that people could use their own filter media.</p> <p>I am not an expert in this and I do not have any recommendations for what kind of media to use.</p> <p>I make no guarantees, this is something I made for myself and thought that perhaps others would find it useful given the current global pandemic we all find ourselves in.</p> <p>I have included the STLs, sliced GCODE and the fusion 360 file as the source so that others can use it to make changes and/or improvements.</p> <p>I hope someone will find this useful. Good luck everybody.</p> <p>EDIT: I first made the "round version" because that design is common on masks but I realized that it would be easier to cut filter material into a square shape than a circle so I made the square version. It should be able to take a square roughly 3x3" or 75x75mm.</p> <p>If you are able to use it or improve it in some way I would love to hear from you.
