Minimal face shield structure.

Mix based on:

• Prusa Face Shield RC2 https://www.prusaprinters.org/prints/25857-prusa-protective-face-shield-rc2
• Protective Visor by 3DVerkstan https://www.youmagine.com/designs/protective-visor-by-3dverkstan

And recommendations received from my local hospital:

• Hold well with no elastic band (easier for disinfection)
• Allow space for masks and glasses
• Lightweight and comfortable

-Designed to optimize material use and print time while still printing easily.

-Hole distances optimized for LEITZ punch hole (80mm distance).
-Also in 80-80-80mm and US 3-hole
-Version with top cover

Please let me know in the comments if you would like other distances.

WARNING!!! READ THIS!!!

-CLEAN WORKSPACE: It is crucial, that your production environment is absolutely clean!!!

-TAKE PRECAUTIONS: Behave like you are infected. Use the respirator and for the next batches ideally the face shield.

-DISINFECT YOUR HANDS AND TOOLS: Wash your tools and hands regularly, if possible use gloves.

-DIVIDE THE STORAGE: Don't store the parts in one place, separate them into multiple batches. Avoid cross contamination! Use sealable bags! The virus is expected to die after 96 hours.

-CONSULT THE DESIGN: Talk to whoever will use this shield (doctors, police, ...). Discuss possible adjustments. One design might not fit all.

Once again, keep your WORKING SPACE AND YOURSELF AS CLEAN AS POSSIBLE!!!
