PRUSA Covid-19 / Coronavirus Face Shield With Integrated Folding Detent Strap

UPDATE 13/04/2020: NEWEST VERSION FOUND HERE: https://www.thingiverse.com/thing:4283205 UPDATE 03/04/2020: A Drill Guide Has Been Added to the Clear Face Shield for Easy Assembly. Use an A4 (8.5"x11") clear PETG shield, approximately 0.5mm thick. You can download and print the drill guide from Thingiverse. Align the guide with the long edge of the sheet and use a 1/4", 6mm, or 7mm drill bit to create the holes. If you plan to make multiple shields, you can stack several sheets and drill them all at once. If the Thingiverse download is not working, go here: https://grabcad.com/library/prusa-covid-19-coronavirus-face-shield-with-integrated-folding-detent-strap-1 In this video, I show my revisions to the popular Prusa 3D printed Covid-19 / Coronavirus face shield. After examining the original design, I identified areas that needed improvement. One of the main issues was the requirement for an elastic strap in the back. This is not something people typically have at home, and it adds another component to the assembly process. I designed a new strap system that can be printed in place, eliminating the need for additional hardware or assembly. Simply remove the supports required for printing, work the strap back and forth a few times, and you'll notice it snap into various positions. This allows you to adjust the angle of the mask closer to your face when wearing the straps at the back of your head. When wearing the straps on top of your head, they should accommodate a wide range of head sizes. The smaller holes work well if you choose to attach an elastic strap in the vertical slots or use creative alternatives like Velcro strips or simple zip ties. The face shield requires a front foam piece for comfort during long periods of wear. I'm using off-cuts of acoustic panel foam, but you can also use paper towels, cut-up t-shirts, or other porous materials. However, please note that these items should be used once and then disposed of due to their porosity and difficulty in sanitizing. Print Directions: * Material: PLA+ * Layer height: 0.3mm * Support: Only on the build plate, do not support bridges Assembly: 1. Remove the supports from the print. 2. Attach the PETG face sheet, which should be 0.5mm thick and the size of an A4 piece of printed paper (8.5"x11"). 3. Use the drilling and cutting template found on my Thingiverse link or the official Prusa site for their version of this mask. If you plan to produce these face shields for others, please practice good cleanliness and research guidelines online for what is required. Do not contaminate the shields and then hand them out to front-line workers! If you have any suggestions for further improvement, let me know!
