the designers who saw Ranee's online request. Flood obtained help from fellow professor Adream Blair and their students，who were learning how to make designs using a 3-D printer."We made a mold(模子) of Shea's hand out of plaster(石膏)，and then we 3-D scanned her hand，" Flood says.

While being fitted in Flood's laboratory，Shea got to choose the color of her new hand. She went with bright pink. She now has a pink hand，a purple hand，and a purple and pink one，and can do things that she couldn't do before，like peeling potatoes，picking up objects，and catching a ball.

Flood and his team have since built hands for six other local children. Indirectly，they have helped dozens more by posting their designs online so that people around the world can print them out. Flood is also working on artificial legs for military soldiers who were injured on the battlefield."Without a covering，the artificial leg is kind of ugly and plain，" Flood says."Soldiers want something that will restore the shape of their legs and make them look cooler when they're playing sports."

As for Shea，the aspiring(有抱负的) musician can now play her viola(中提琴) with the help from an adaptive device that Flood's team created."Nothing is ever going to hold her back，" Shea's father，Steve，told a local reporter.
