A 3D printing company is giving away for free its design for a device that allows doors to be opened handsfree - here's how it works

The design consists of two detachable pieces.

To make installations easy, the handles don't require drilling holes or changing the actual handle.

Instead, the pieces attach over the door handle with four screws.

The shape of the new door handle allows people to open doors with their arms, avoiding directly touching with their hands.

Of course, these door handles can also become contaminated, and Materialise still recommends disinfecting them regularly.

The current design works for door handles, but not doorknobs.

Materialise is giving the design away for free online, for anyone able to 3D print to use.

It is also encouraging others to modify the design for other types of doors, and distribute those as well.

Materialise told Business Insider that its team took just 24 hours to create and test the design.

Assembly instructions show how the pieces come together.

The team even came up with a slogan to go with the design: "Do less harm. Use your arm."
