Covid-19 Face Shield-> German Standard <- (like Prusa Face Shield) by CR-3D

thingiverse

Check out our new design with landscape foil and DIN A4 (888) holes! Thing 4279712 Please read this description and for assembly, please look at the video! We set this design as the standard for Germany. 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 picture. For example, we use the following sheets: https://www.falambi.de/einbanddeckel/din-a4/100-deckelfolien-din-a4-transparent-klar?number=25006 The following was used as a rubber band: https://www.amazon.de/gp/product/B01LZE7IEN/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1 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 Source Josef PRUSA Licence and selling of face shields We share these files under non-commercial licence. It would be great if you donated these shields to those in need for free. If you need to cover your production costs, we are ok with you selling the shields for production cost. However, we do not want to see these shields on eBay for €50. Also commercial 3D-printers are allowed to print this file and can cover the production costs! Update 26.03.2020 - Afternoon Added a stack with 6 shields -> there is a gap with 0,2mm between the parts Update 26.03.2020 - Lunch Changed the Belt Holder on the back side -> Mask_frame_C5_CR-3D.stl Update 26.03.2020 I will order and test a thicker film (0.3mm)! Added a new Version -> Mask_frame_C4_CR-3D.stl Changelog: - The height was reduced by 2mm - the thickness has been adjusted - the cover plate has been removed (Would be optional but possible) Added different bottom frames for different shield thickness -> for a 0,2mm Shield the 0,3mm bottom frame works fine for me! Old Version -> Mask_frame_C3_CR-3D-small-file.stl 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.
