3DVerkstan V3 - Face Shield

Submitted in collaboration with and with permission from the 3DVerkstan team.

There is a shortage of protective gear for doctors and nurses, so we've designed a frame for holding standard sized plastic sheets. Quick to print, easy to assemble.

Since the medical community currently has a urgent need for protective visors and other PPE for our heroes that spends their days battling COVID-19, the team at 3DVerkstan has spent a lot of time during the past few days designing a printable visor. It is quick to print, has minimal material requirements and can be easily assembled.

The plastic shield can be made out of any semi-stiff plastic sheet between 0.1 and 1mm, including overhead film, cover sheets for binding machines etc, as long as it is available in a suitable format.
 

The mounting pattern for the plastic shield has a 6-Hole Pattern achieved by punching twices with a 3-Hole Punch with a 1" offset between each set. Note: orginal attempts using only a single 3-hole pattern were not sturdy enough.

The 3DVerkstan design was created to be simple but effective as possible with these goals in mind: 
 

- Use readily available plastic sheets with little modification needed and then only with common tools
- Simple geometry which is printable with small to large nozzle sizes - 0.4mm up to 1.2mm - and thin to thick layer heights - 0.25mm up to 0.6mm 
- Provide drip protection above the eyes
- Printable in under 20 minutes
- Avoid tight tolerances which require well-tuned printers
- Ensure printabilty across a wide range of common materials (PLA, CPE, PETG, ABS etc.)

Notes: 

-If you need it to sit tighter on your head or if you are leaning over patients a lot and worry about it falling off, a simple rubber band can be put over the two hooks in the back.

I would like to thank the fantastic team at 3DVerkstan who all have contributed massively! Additonally Erik Cederberg, for helping optimize the design for the USA and provide additional information to help me publish this project here.
