My first round of #COVID19 protective face shields are used in a real environment since yesterday evening. Everything went smooth but I have to made few adjustments:

The nurses found a weak point (understand: it broke) at the connection of the curved structure and the strap. A revised version (outside) has a smoother transition between the curved part and the strap.

You can also notice that the shoe-horse pattern is wider. Here the new model is outside. The tight form was not adapted to resist compression forces

I also increased the overall thickness. The cost is an increased printing time (+6min) and more filament (+30cm), but I hope it will improve overall the robustness

This is the new look of the 3D printed part. Prints in 25 minutes, and uses 2.66 m of filament. In one day, a single printer can print 20+ parts, a spool of 1kg can make 120+ parts

As usual, download the 3D models and the settings in the Github page: https://github.com/marcteys/ECOvid-FaceShield #opensource #3Dprinting #b3d #3dprinttosavelives
