Summary

Please consider clicking the "I made one" button and sharing pictures of your print ^^
If you like my work give me a like, it means a lot to me.

Made this design for myself with stuff i had at home

You can mix V1 and V2 parts as following
BaseV1 + SupportV1 + Cover V1 (3 parts assembly)
Base V2 + CoverV2Grid + CoverV2LockRing (3 parts assembly)
BaseV1 + SupportV1 + CoverV2Grid + CoverV2LockRing (4 parts assembly)
Base V2 + Cover V1 (2 parts assembly)

60mm Round cotton makeup remover pads are great particle filters and also very cheap (Around 0.01$/piece here)

print at least 2 pairs and change the filters every 2 hours.

Compatibility
3M™ Half Facepiece Reusable Respirator 6000 Series
3M™ Half Facepiece Reusable Respirator 6500 Series

Protect yourself.

one pad is sufficient (also works with 2 pads in 1 holder but adds a bit of breath restriction)
