3M adapter to Sperian Survivair cartridge

thingiverse

This is how to convert the Sperian Survivair cartridges for use on a 3M bayonet-style mask. The mask I'm using here is from the 6000 series, but this should work with most models as long as they have male bayonet fittings. I built this adaptation by combining two existing projects - user RoJSimpson designed the threads, and user VinnytheKnight created the bayonet portion. If you've got a bunch of Sperian filters but no mask, this might be just what you need. The overhangs are a bit rough because I didn't use any supports during printing. To get them to turn out smoothly, try using 100% infill and be prepared to snip off a few small strings afterwards.
