The vivacious two-year-old was born with no fingers but a nub for a thumb and a quarter of a palm on her left hand, from a condition known as Symbrachydactyly.

Detected at 20 weeks in utero, she is one in 30,000 whose finger bones haven't properly formed, leaving nubbins for fingers.

Libby has since defied the odds to conquer the simple things in life, with the help of a robotic hand, made from a 3D printer in Wagga.

"She proves to everyone that nothing will stop her," her mother Jacinta Evans said.

"It's the simple things in life, like eating with a knife and fork, tying her shoelaces.

"It's the things in life we take for granted."

Libby received her new hand on Thursday after a trial run in September, which she quickly adapted to.

A sister to Abbey-Kate, 4, and brother Michael, 1, Libby defied timeframes that estimated she'd take six months to adapt to her new hand.

Four-and-a-half months later, she can now ride her bike with both hands for the first time.

"We were dumbfounded," Mrs Evans said of Libby's taking to the hand.

"She turned around to Abbey and said, 'I did it'.

"She didn't know what to do.

"She high-fived everybody."

While Libby's condition has never slowed her down - she was crawling at five months and walking at 10 - it's been a battle for the family.

"We were told she was too young, she won't know how to use it," Mrs Evans said when she first approached an Australian company about a hand.

They were told to wait until she was at least three, so instead looked into sourcing one from America, which would have set them back nearly $6000.

Mrs Evans approached Precision Signs in Wagga, a company that specialises in technological developments.

She paid less than $100 for Costa Ligakis to print a robotic hand on his 3D printer.

"It was a trial and error," Mrs Evans said of the first hand.

"It's easier to move now."

It took just several weeks to formulate the plastic hand that uses fishing line and elastic to move from her wrist.

Mr Ligakis used a recently purchased 3D printer to make Libby's hand, after building his first while nursing a broken leg.

"A 3D printer takes a 3D image, slices it horizontally like an MRI, lays down each slice on top of one another and prints out," he explained.

"It's very cheap, the materials would have cost no more than $5.

"I'm happy if anyone wants to make one, I'll make one.

"When Jacinta showed me the file, I was horrified (about the cost), especially for a little kid.

"If I can help anyone else, I'm willing to try."

Libby has worked closely with an occupational therapist at Riverina Hand Therapy since she was one.

"She came to me as her parents were keen to access local supports for their daughter to help her function with her hand difference that she was born with, Libby's hand therapist Amy Geach said.

"Libby has an amazing family that have continued to explore ideas that enable Libby to do all the things she enjoys, and to reach her milestones in development, such as feeding herself. "

"The 3D printed splint provides Libby the use of fingers that she would not otherwise have.  

"When the splint is on, Libby uses her wrist movement to power the 3D printed fingers to open and close via a specific pulley system.

"It is powered by Libby's own wrist movement.

"The opportunities for this not only now, but into the future are very exciting for Libby, giving her the ability to grasp items such as a drink bottle, and use her hands together for play and learning tasks such as holding a cricket bat.

"The splint will need to be adjusted as Libby grows, and at present she is still getting used to wearing it and working out herself what if can be helpful with. She gives a mean high five to everyone in our rooms when she visits."
