"Calling all industrial designers, model makers, painters, builders and those in the trades: Our industries use the same masks that are currently protecting the doctors and nurses on the front lines of this pandemic. We know that they are running low on N95 masks.
"If you know of any stockpiles of N95 masks in your woodshops, model making studios, workshops, or supply cabinets--hospitals are currently taking donations. These masks are critical for them to stay safe and help those in need. Please reach out to anyone you know who might have N95 masks and urge them to donate them to their local ER. If you have masks, call your local hospital and ask if they are taking donations."
A note I'll add: I assume hospitals will not accept the masks unless they are still in their packaging, so check yours.
