Covid-19 Protective Face Cover (like Prusa Protective Face Shield) by CR-3D

We have been receiving more and more requests for so-called face shields in the past few days, which is why we have developed a variant that has been optimized for us:

Important:

The design was based on that of PRUSA, but I completely redesigned and designed it and, in my opinion, incorporated a few updates. I didn’t have the initial idea for such a face shield, Josef PRUSA had it, but I changed it by a few points.

For one thing, I completely closed the gap between the shield and the head with a base plate.

I have optimized the file regarding printing time. I removed all senseless openings and I reduced the height and was able to reduce the printing time significantly

Another very big advantage:

With our variants, you can use a simple A4 sheet cover and drill the 4 holes with a conventional punch. These must be attached as in the attached drawing.

For example, we use the following sheets:

The following was used as a rubber band:

So anyone who owns a 3D printer can easily produce and provide such a shield. Please share this design, improve it and produce it for everyone who needs it.

Version C3:

You can use standard DIN A4 Sheets and a conventional punch for creating the shield itself.

If you want to manufacture shields for others PLEASE READ THIS CAREFULLY

Act as if you were infected by the COVID-19 virus.

Wear a face mask and a fresh pair of gloves when collecting each batch of printed parts. Store the parts immediately in a sealable bag.

Talk with whoever you’re making the shields for, let them know about your manufacturing environment

There is still debate about how long the virus survives on plastic, but most sources mention 2-3 days. That means that by letting the packed face shields sit for 2-3 days before distributing them, you’ll greatly reduce risk of transmission

Do not store the entire stock in one place, minimize the risk of cross contamination
