I apologize if there is already a thread for Face shield designs that don’t rely on 3D printing the headpiece. The University of Illinois worked has designed a face shield that can be fabricated relatively quickly using waterjet or CNC. The design can be seen here and, upon registering, teams can have full access to the design files. (If you register, be sure to actually save the link that is provided because at the present time, a link that is e-mailed to you won’t work). https://covidppe.grainger.illinois.edu/
FRC team 4096, Ctrl-Z, fabricated some prototype shield visors for this design out of PETG and we are now planning on fabricating shields using HDPE for the headpieces so the 3D printers can be utilized for other projects. We will most likely modify the UIUC design and add two more “nubs” so the present visors we use on the Prusa frames will fit this UIUC design.
Hopefully, we can quickly get the design imported into SW and run the CAM and start cranking out new shields in a few days. We plan on using an Onsrud 63-762 bit to cut these; we are already using this bit to cut visors out of 0.030 PETG.
If any teams use this design, please post here as I have been promoting the fact that FRC teams will be able to make thousands of these.
