Mask Exhalation Valve
thingiverse
Remix from: https://www.thingiverse.com/thing:4273532 This remix provides better tolerances for the threads to work when printing on a printer similar to the Ender 3 (the original design is too tight). The valve cap has also been redesigned to provide side exhausts and tolerances to snap-fit with the valve body. The tighter valve and nut version is slightly tighter if you prefer a bit of friction while threading.
