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 discription and for the assembly please look at the Video! We set this shield as the standard for Germany! - At least a DIN A4 foil with 0.3mm was used as the film thickness. - An additional mounting of the shield by a bottom frame was not considered important, which is why this will be dispensed with in the future. - On the inside of the forehead support we use a foam tape to further improve comfort - the DIN A4 shield does not have to be the entire length. it is recommended to shorten the shield by approx. 50mm in order to be able to turn the head even better with the shield You can use a simple A4 sheet cover and a conventional punch! just keep a distance of 9mm from the edge so that the film can be pulled tight -> These must be attached as in the attached picture. Look at the Video please: https://www.youtube.com/watch?v=HRj5M-juj_0&feature=youtu.be&fbclid=IwAR0zWeVT8GVCZvC7DJT2OT7f1cMzPbXBfntMuUvxdaEu_QNSWnlosjslfp0 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 Licence and selling of face shields (same regulation as PRUSA -> Source PRUSA) 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€. +++ Updates +++ Update 06.04.2020 Uploaded a Stack Version with 4 Pieces. Thank you a lot Phillip Stinner for creation! :-) Update 01.04.2020 Added a first STACK Version with 5 Parts and an gap of 3mm between the parts. Please test it and give me a feedback! perhabs anyone has a better idea... Update 28.03.2020 Added a Picture how to punch the A4 shield Added a PDF as Template for the Shield Added a .dxf for lasercutting --- Update 27.03.2020 afternoon -> after coordination with "Deutsches Rotes Kreuz" -> File: German-Standard_DRK_FaceShield_Mask_frame_C7.2_CR-3D.STL -> the white one in the pictures -> Series production for hospitals in Germany has started!!! Changes: - The visor was moved further away from the forehead - This allows a better fit over bigger respirators and protective goggles - Total height set to 12mm -> for better wearing comfort - better mounting of the rubber band and for easier printing (Downskin) - Overall length has been reduced Important: We made these changes together with the Deutsches Rotes Kreuz (DRK) and these were found to be good for Germany. --- 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. 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.
