3D model description

Handy multipurpose tool is an open source, 3D-printed, personal device to be used every day to pull or push a door handle, to open the car door, to push a button and to easily grab grocery bags.

Check the video here:

The idea behind Handy is to offer an open source response to COVID-19 outbreaks, which is known to reportedly last on some surfaces for days.

Having a personal multipurpose tool to avoid direct contact with handles, buttons, bags and other daily objects outside of our home, helps to increase hygiene and to lower chances of getting infected.

Handy can be 3D printed at home, via online 3D printing service, or for those who are creative manufactured by cutting and gluing layers of cardboard together. This might be a fun activity to do with kids.

Handy is customizable, easy to carry, personal, ergonomic (with its design that fits fingers of any size, and limits the hand torsion), can be used by right or left-handed individuals and it’s easy to sanitize.
