Printed Door Opener to Help Against the Spread of Coronavirus

Hello!
thanks for this great idea, printed one, unfortunately i have curved handles, and i am only fluent in openscad, so i redesigned it for my needs : https://www.thingiverse.com/thing:4233677
also since i am in quarantine (thus no acces to hardware stores,) but in the need to equip the consultation (?) of my wife with those, i halved the need for screws, if ever you like that idea....
still searching for a way to get rid of all screws, since my wife opens the doors in a hurry and manages to turn regularly the handle, getting her hand in the way of the screws (any ideas welcome!).....
