The team of University of Central Florida students who built a prosthetic arm for a little boy on a 3D printer is now building a partnership to help children around the world.

Back in July the students built an arm for Alex Pring for less than $350 and gave it to him for free. They then uploaded their designs onto the Internet for anyone to use.

Since then the team has gotten requests for help from 22 countries around the world.

To help with demand, the team built a partnership that they can contact to help with requests. Some of those institutions include Johns Hopkins Hospital, Miami Children's Hospital, the University of Southern California and the University of Pennsylvania.

However, UCF reports the students have also traveled to help fit some of the prosthetics. Three team members drove to Virginia to fit a 7-year-old girl with her new arm by Thanksgiving morning.

One of the team members said they help to someday work with the United Nations and UNICEF to set up 3D stations around the world to help every child.
