Face shields and mask extenders (COVID-19)

With the current COVID-19 pandemic, many hospitals are running out of personal protective equipment for health care personnel.  I am a STEM teacher, and my school district is allowing me to use our 3D printers to help alleviate some of the problems.  I plan on printing mask extenders to help people who are wearing masks for 12 hours shifts so that their ears are no longer irritated by the elastic of the masks.  I also plan on printing the face shields in the above picture which have been approved by the FDA for use.  While I have the 3D printers, the filament to print these is rather expensive.  I'm looking for donations to help me complete this life-saving project.  Any help at all would be greatly appreciated!  The quicker I can get these printed, the better.
