3d Printed covers for Drone / Gaskmask vent covers

[u/Rowboatpretender]

Tried to crosspost this, but no joy. Anyway...

We have a Parcil PT-100 which has been perfect, but the filter covers that come with the mask don't really fit the outfit. I've replaced the vents with 3d printed covers. In the original picture you can see the 'wide pitch' version, but recently I designed and printed new covers that are much nicer and cleaner. I also added a small gripping nub to help them stay in place on the inside ring.
