NEW Covid-19 Face Shield Design (Prints ~4X Faster, No Elastic Required, Printable Straps!)

thingiverse

In this video, I'm excited to share my latest 3D printed Covid-19 face shield design! After many iterations and combining the best features of popular face shields, I believe this design offers great protection, comfort, and ease of use. Like my first design, no elastic is required, and you can easily 3D print the straps! The big advantage of using 3D printed straps is that it eliminates one more part to source, and they are easier to clean than elastic straps housed in fabric. Nurses and doctors are forced to reuse their PPE, making cleaning a challenge. Foam/fabric cleaning tools can harbor bacteria, viruses, and other contaminants. The straps can be printed in PLA or TPU, with both files provided below. I recommend using TPU as it is extremely tough and flexible, but PLA works just fine! In addition to the easy-to-use and clean straps, this new face shield offers more protection from overhead due to its top cover! Despite all its features, the print time should be approximately 4 times faster than my previous design due to its slim design. I have also included a drill guide for the clear plastic front shield. I recommend using 0.5mm thick material such as PETG for your face shield. The drill guide has two hole settings to adjust the clearance to your face. Many popular face shields in circulation have too much clearance under the chin, but my offset hole design fixes this issue! Despite the holes being offset, the pattern still fits the PRUSA RC2 masks, so you can use this hole pattern to bring those shields closer to the wearer's face. This design is also compatible with my previous design if you prefer that one. I made the lower chin piece from the PRUSA design more robust, as I found that the original model was thin and not strong enough for continual use. They prioritized print speed over durability. If you have any questions about print settings, please see the print details in the Thingiverse link or ask me in the comments section. Design files: • You can find them here: https://grabcad.com/library/prusa-covid-19-coronavirus-face-shield-with-integrated-folding-detent-strap-1 Print directions: • Material: PLA • Layer height: 0.3mm • Support: None Assembly: • Attach the PETG face sheet using the holes (see drill guide file) • The sheet should be 0.5mm thick and the size of an A4 piece of printed paper (8.5"x11") • The drilling and cutting template can be found on my Thingiverse link • The lower chin piece slides onto the clear shield with ease If you plan to produce these face shields for others, please practice good cleanliness and research guidelines online. 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!
