How 3D Printing might help against COVID-19

Thinking of how 3D Printing might help the fight against COVID19? There are many 3D blueprints online, ranging from handle hooks and door-opening tools, to reusable masks and eye goggles. Researchers from the HP-NTU Digital Manufacturing Corporate Lab designed two new 3D models of handy tools: a door opener which can be used to press lift buttons and an MRT/bus handle hook, which could be useful to reduce contact with surfaces and reduce potential exposure to viruses. They also tested designs for masks and goggles downloaded from the following websites. Which 3D printed tools do you think are most useful during the COVID19 pandemic?
