yes!! truly necessity is the mother of invention.. and here comes the story of Monash University Engineering student has used 3D printing to develop a cheap and safe plastic tool that can open doors and push buttons – eliminating the need for hand contact on potentially contaminated surfaces in the era of COVID-19.
When asked what inspired him to make something like this he said that he had seen a video online where some people were touching elevator buttons after sneezing and coughing.
Muthu’s invention is not the only one that inventors have come up with. Steve Brooks, owner of DBB Ltd, a company that manufactures office furniture in London has developed something called the Hygienehook. This is a metallic version of Muthu’s smart key and serves the same purpose.
Muthu said that he is making the design and the procedure to make his smart key tool free for anyone who wants to develop it using a 3D printer.
Currently, the invention isn’t in mass production. However, a lot of countries have shown their interest in manufacturing something like this.
