3D Model of COVID-19 protease generated with oscilloscope. The protease is studied in order to learn how to block it so the virus cannot replicate. Profits from this work will be donated to Save The Children https://gitcoin.co/grants/494/save-the-children for COVID-19 expenses. It has been created from a 3D model of the COVID-19 main protease from the US National Institutes of Health https://3dprint.nih.gov/discover/3DPX-013157 Digital Object Identifier (DOI) 10.2210/pdb6Y84/pdb
