Disney is backing a startup that offers 3D printed prosthetic for children at the very reasonable price of $500. Iron Man, Elsa from Frozen, and a Star Wars themed one is up for grabs. Engadget writes:

Open Bionics is part of the 2015 Disney Accelerator programme, which explains its choice of characters. Still, the ‘House of Mouse’ has been gracious enough to provide royalty free licenses, as well as time and input from its creative teams. The three versions are fitted with LED lights and, in the case of the Iron Man model, a vibration motor for when the user wants to fire a “rocket.”

Sure, the startup is part of a Disney project, but it’s still pretty darn great for kids. Prosthetic limbs are usually very expensive.
