Face Mask Vent Cover (Plug)

This is a vent plug for face masks that come with vent holes. This is used to prevent exhale particles from exiting through the vents and infecting others with your potential illness. I'm not sure if this will qualify your mask in areas where masks with vents are not approved,, but if it does, here you go :)

I also included a blank stl so you can put your own image on it if you don't like the biohazard symbol. I cut the img I used into the top by 1.5mm, which looked like a good depth. The total depth of the cap is 2.5mm, just for your reference.

For printing, flip the plugs so they lay on their face so you don't need any supports. It's only face up on here so you can see it better in the preview. Doesn't matter what type filament you use. Just be aware they you'll have to smell it on the inside, if you use something with an odor.

Edit: Added a new version with ribbed edges to grip it better when assembling. Also added a pic to show what it would look like if you used 2
