Front Line Face Shields

I have been self funding the 3D printing of face shields and supplying them free of charge to front line staff for the last few weeks. My plan was to continue funding this myself but I had no idea how much of a shortage there was for these shields and I am being inundated with requests and have just purchased my second printer. If you could spare any size contribution to assist me with this activity, it would be very much appreciated. Many thanks, Paul
