I'm surpirsed to have seen more in reference to the 3D printing community coming out from the IET. We've become involved with https://www.3dcrowd.uk/. Using our own 3D printer to manufacture parts for face shields. I'm sure there are others in the IET with their own 3D printers who have their own 3D printers and can manufacture them.
Also there are nationwide initiatives for those of us with experience in sewing to manufaccture scrubs for hospitals and those in care settings, (search 'For the Love of Scrubs', and find your local group from there). These are absolutely practical ways in which this community can and should be helping, even if it's via financial donations or supplying spare bed sheets to those sewing scrubs!
