PAX to gasmask magnetic quick connect

This is a magnetic quick connect adapter for 40mm NATO gasmasks. If you don't want to mess with magnets, just print the solid version. Otherwise there are swappable magnetic attachments. Included .f3d files make it easier to create other tops in Fusion360. Thanks to ThatDrewLion for the original model this remix is based off. In this modification, the PAX adapter has an extra hole you can use to adjust the ratio of fresh air coming through. There's some variation in PAX cartridge dimensions, so if yours doesn't fit, try dipping the vape end of the adapter in hot water and reforming it around your specific cartridge. I've printed in matte PLA, but that adjustment should work with other materials too.

For the magnetic version, you will need some 6x2mm neodymium magnets and glue for assembly. If you don't want to screw around with magnets though, there's a solid version included that requires no extra parts.
