Gasmask Insert 40mm Nato

This is a insert for gasmasks which use a 40x1,7" Nato thread. It's Purpose is to protect the intake valve while still letting air pass through for easier breathing while cosplaying or playing airsoft while still having a filter installed meaning it's use is meant for gasmasks able to take 2 filters but use it on what you want. (!Warning! using this on a gasmask makes it not protecting you from any airborne threats or similar and is only for use in safe areas)

I recomend using some robust filament.

I hope it helps some of you with breathing while i would not recomend using a gasmask for airsoft without training.

Also i am not responsible if you somehow get harmed by it should it splinter or break when hit.
