Copper 3d's "solidrim" face mask fits my face pretty good, but the version you can download at opensourcemask.com (or https://copper3d.com/stl/gfacemasknanohack.zip) comes without a logo (or other pattern to increase airflow).
Good thing the CC BY-NC 4.0 license allows remixes!
As Lost World Order are about to play their last concert in december (see https://metalconspiracy.de/ for more info on that), their old logo (from "This Apparatus Must Be Earthed!") has the right shape and "Endzeit Thrash Metal" goes well with face masks anyway, I extracted that via Inkscape and stamped it.
Furthermore I wanted to use the headstrap from some old ski goggles, so I altered the fixture for that. Zip ties now affix the strap.
Copper 3D stuff for this specific version is included, but I left out the version with separate rim here.
Read their explanations - I reject any responsibility for health issues.
This is NOT personal protective equipment (PPE).

Edit: The upload-issue commented on seems to be solved. :-)
