Face Shield for US Letter 3-hole Punch

thingiverse

This is a more streamlined version of the face shield made by Prusa and others to help with the shortage of face shields in hospitals and long-term care facilities. It uses quite a bit less plastic to make what PETG you have on hand go much further. It is also formated to work with standard letter-sized 3-hole punch page protectors available in the US. You can use an elastic strap for the back connection, or I have found that two #33 rubber bands put together work really well too.
