Rather than wait 18-months for his son to receive a bionic hand, a dad decided to make his own.
Callum Miller bought a 3D printer and created nine sets of bionic limbs for his 11-year-old son Jamie.
Complete with flashing lights, he was able to build the bionic arms using tutorials on YouTube, as well as help from online forums.
The father from Stockton-on-Tees told Sky News: I knew nothing at all about it before we bought the 3D printer.
The nine bionic hands have all been made in different colours, with one even styled with a Batman logo.
Mr Miller continued: Jamie comes up with designs as well as I do, including a steampunk one which is gold and bronze. We just fire off ideas at each other, really.
Jamies preferred arm is the steampunk one.
Jamie said: First of all, it just looks amazing, and say if Im going to a party the lights show off a lot. Its not too bright but it looks really cool.
The two have plans to make a more advanced arm.
Mr Miller said: It works on myo sensors, which are little sensors which sit on Jamies muscle on his arm and we plug them into the laptop at the moment but it has a little board that takes the programme.
When Jamie moves his arm the fingers open and close. At the moment its quite mechanical.
The idea of this [new] one is that itll be Jamies muscles and technically him trying to move his fingers so it will sort of be a semi-bionic arm on its own.
The arms designed by Jamie and his father have enabled him to hold and carry more things, as well as to catch and throw a ball.
Overall its made him more confident with himself, Mr Miller said, adding that others across the world have done the same.
Instead of hiding away a disability, theyre more happy to show that theyve got one because theyve got something cool to show off.
The two have also been collaborating with charity Team UnLimbited, who provided the family with a better 3D printer.
