I tried printing a face shield and found it to be very uncomfertable. I can imagine that being a problem for someone working long hours.

I designed these clips to turn an ordinary baseball hat into a face shield. The clips are small and can be printed in less than an hour.

They are also adjustable to what you have on hand for a shield.
