I use a Glowforge laser cutter, which works from SVG files. I converted the DXF to SVG, and I am sharing it so that others don't have to deal with the hassle.
This is the face shield laser cut file, converted from DXF to SVG for use by laser cutters, such as the GlowForge, or routers such as Shaper Origin, which work from SVG rather than DXF.
The author remixed this model.
