In reaction to the acute shortage of protective wear for medical personnel in the current pandemic situation, we have quickly developed and started to mass-produce protective face shields. We have already printed and donated over 12.000 shields to medics and other professionals in the Czech Republic and we have requests for 90.000 more. But the shortage is global and everyone with a 3D printer can help! 3D printing communities across the world became a massive driving force in the effort to produce protective wear for those, who need it the most. This is why the design of the shields is fully open-source, anyone can produce it and/or modify it. Also, the shields are made from easily accessible and inexpensive materials. We would like to ask you to help us by spreading the word or even joining the collective endeavour - as a community, we can help thousands of people in need.
