Six-year-old Keira Campbell has a new arm thanks to 3D printing

Six-year-old Keira Campbell has shown her class her "perfect" new arm thanks to a man whose son was also born without a hand.

Callum Miller, from Stockton-on-Tees, bought a 3D printer to make an arm for his 10-year-old son Jamie.

Keira's mum Nikki Talbot got in touch with him and asked him to do the same for her daughter.
