Anti-viral door handles (Task 1, Option 2)

 I remember reading this news article a few months ago about an Australian company which uses 3D printing to coat door handles with copper to help reduce  the transmission of viruses. I thought it was a timely demonstration of  how  technology is being used to solve a current real-world problem, in a cost-effective way. Copper has long been known for its antiviral and antibacterial properties  but has been too expensive to use on a large scale.
