thingiverse

The DtM-v3.0 face shield PPE design has been thoroughly reviewed and approved for use by the USA National Institutes of Health (NIH). Check out the design on the NIH website here: https://3dprint.nih.gov/discover/3dpx-013359. Files included in this post are two versions: -- DtM-v3.0 for US and Canadian letter-size transparencies and three-hole punch -- DtM-v3.0-A4 for A4-size transparencies and the ISO 838 (888) four-hole punch The USA Food and Drug Administration (FDA) has guidance on 3d-printed PPE here: https://www.fda.gov/medical-devices/3d-printing-medical-devices/faqs-3d-printing-medical-devices-accessories-components-and-parts-during-covid-19-pandemic. DtM-v3.0 Face Shield - Graphical Instructions for Use https://drive.google.com/open?id=124-gOXaXDoSyl-VApn8imYEQTtP6LLYI2Z3Au1uhq3U We were inspired by the Prusa RC2 design, which showed incredible leadership in a crisis. In the last week, we have assembled a team of over fifty experts in design, engineering, and medicine with volunteers from Spark Health Design, Microsoft, and Boeing. Clinical experts from Mass General Brigham, the University of Washington Harborview Medical Center, and the UW Medical Center at University campus joined us too. Working nonstop in groups spread across the country, we have completed three very fast cycles of prototyping and clinical testing. Our remix focuses on improved protection for the wearer from aerosol and splatter from above, improved washability, and re-use. The final design, DtM-v3.0, along with instructions for fabrication and assembly, has received US National Institute of Health (NIH) recommendation. Find the latest reference files for the version with three transparency mounting pegs that fit a standard US three-hole-punch here: https://3dprint.nih.gov/discover/3dpx-013238. The files posted here on Prusa Printers are for DtM-v3.0-A4, the same DtM-v3.0 design, with the four-peg layout from the original Prusa RC2. These pegs are compatible with an ISO 838 (888) style four-hole punch for A4 paper. We have released this design under a public domain open license so you can use, remix, and build upon our work, which itself builds on the Prusa team's design. Let's work together to protect frontline healthcare workers!
