Replacement 3M Inhalation Gasket and Valve
Description
These are TPU replacements for the 3M inhalation port gasket and inhalation valve cover. Install the valve with the slightly raise part facing the direction your face will be, this will help keep it in place. I've tested the gasket on a couple masks, if it is too tight for you, you can make it 0.25 - 0.75mm thinner using 3D builder (which is free on every windows 10 pc) or the program you are familiar with if you have one. DON'T alter the valve though or it won't work. You must print at 0.1mm for them to come out properly. These parts are almost impossible to get right now and jerks that do have them are charging the cost of 20x for a single one. So enjoy!!!
