3M Face Mask Respirator Filter Connector with Orientation Marker
Description
This is a connector to interface with 3M respirators. This is being developed in response to the COVID-19 pandemic threatening humanity. Due to the shortage of N95 masks and respirator filters, I'd like to be able to develop the ability to create replacement filters for existing face masks- I got this face mask a couple years ago for spray painting projects, and now I am trying to re-use it as protection. I will be experimenting, starting with the connector as the base, with creating COVID-19-blocking filters from accessible resources and materials. By Thursday, I will be releasing my first filter mount design, utilizing HEPA filters from vacuum cleaners, as they are readily available in supermarkets and ship within a week on Amazon. Other materials I'm looking into experimenting with include car air filters, HVAC air filters, and cuts of fabric. I am aware that 3D printed parts often contain holes and gaps that a virus can fit through, so I'll also be looking at finishing process to seal any holes and gaps. Hopefully something as easy as a clear coat can work. I am including the Fusion 360 file to maximize possibility of modification. Autodesk Fusion 360 is free for individuals. You can download it and export the included source file to import this into other CAD programs if you wish to. I own a 3M Half Facepiece Reusable Respirator 6100, which I used for the development of this connector. The tail marker on the connector is used to help orient your designs- the tail should point backwards, at least on the 3M 6100. I spent a good trying to make it as even as possible, left/right. The picture of two of these mounted on the face mask is proof of the balance. Let me know in the comments if this holds true for other 3M mask models.
