BELTON, MO (WDAF)-Kellie McClanahan's daughter, Madilynn, has diabetes. Her pump delivers insulin to her 24-7.

“It’s her lifeline, she has to have her pump, if she doesn't have her pump, she needs to be on shots.”

Thanks to one of Kellie’s friends; her daughter’s American Girl doll now has an insulin pump too. David Rinaldi, of Belton, Missouri, made her doll a pump to match her own with his 3D printer.

Madilynn said, “It makes me feel comfortable, and it feels like I have someone else in the family who has diabetes too.”

Kellie, who now lives near St. Louis, and Rinaldi, were schoolmates. She saw on F that he had bought a 3D printer and asked if he could make an insulin pump for her daughter’s doll

“Within minutes, no hesitation, he's like I can do that.”

Rinaldi has three young girls, and says he'd want someone to do it for them.

“If they wanted their doll to look just like them, and it was something that wasn’t out there, I’d hope somebody would help to create that to make them feel better,” said Rinaldi.

Kellie says she's asked American Girl to make diabetic supplies for a while.

McClanahan said, “That`s what American Girl is about - make your doll like you - you can have glasses, you can have hearing aids, wheelchairs, food allergies, epi-pens...but they don`t have an insulin pump.” She added, “Luckily I had a good friend that can make that happen.”

Rinaldi builds an object on a computer; a small motor runs the 3D printer that melts the plastic into the shape designed on the computer

“It builds at about a quarter of a millimeter at a time, and builds layer, after layer, after layer,” Rinadli explained.

Rinaldi made this insulin pump, a blood sugar transmitter, and receiver for a doll that is now just like Madilynn.

WDAF reached out to the American Girl company which says a specialized item that will speak to girls with diabetes will be coming out in January 2016.
