Minimalistic design optimized for mass production. It uses only laser cut plastic and two rubber bands. The shield is surprisingly comfortable to wear and stays in place even during violent head movements. . We used 0,5mm PETG sheet, but any thin plastic should work. It takes 1m30s for our low power laser to produce a shield and under a minute to assembly. Rubber bands are 9cm in diameter. Again it's easy to adapt any elastic material. It's based on excellent idea from Prusa https://bit.ly/33Erl15 . Feel free to use it under CC BY-NC 4.0 license to help hospitals in your area. Let's hack this pandemic together! .

i have really good news for anyone who is producing or want to produce our shields in big numbers and sell them to those at need. We have just posted our own, well crafted license agreement that was made by our marvelous colleagues who knows something about licensing law :).
Don't be afraid, our license is very permissive, you can make money producing our design. If you are preparing to start commercial production, please take few minutes and read posted agreement.
As always, if you do have any questions, please leave a comment.
After countless prototypes and hundreds of ideas we can now present you second version of our shield! There is a lot of new features:
Wider shield
More coverage for ears
Plate on back of the head for people with longer hairs
Cover cup on top (also laser cut!)
Much better locking mechanism, huge thanks to @dylangunn and his brilliant design!
Also, we've removed front bottom rubber band. It felt useless and only added unnecessary element.
Great thanks for whole community, ideas you gave us and the pace of new iterations are astonishing. We are sure there will be more from us so lets keep in touch!
Awesome idea guys. One thing though - why submit it as a .dxf? I just spent 30 minutes trying to find a way to convert it to a png and to also read the file to get it's dimensions.
(it's 380mm wide, 240mm tall. the band is 250mm x 30mm)
.dxf is common format to use with laser cutters. But this is great idea, i will upload right scale .pdf with marked dimension. May I ask You, why do you need .png? How did you cut it?
I use an Emblaser 2 with LightBurn. I know that it can import images. I don't think that it will import dxf. I haven't cut it as I don't have access to the plastic.
