So Jude Ryder went to her son Dale, a mechanical engineer. Dale was only 8 when Mrs. T joined the family. He designed her a set of snazzy wheels borrowed from model airplanes, and now Mrs. T can get around just fine.
"It was like fitting her with a turbocharger - she's going double the speed she used to," Jude Ryder told the Telegraph. "She uses her back legs to push herself along. She seems quite happy, but it's difficult to tell with a tortoise."
Ryder added that at 90, Mrs. T is "still quite young for a tortoise" and could live another 50 years.
Mrs. T isn't the only pet to get a mechanical upgrade to help her out - 3D printing is an awesome way to design the perfect prosthetics for animals who need them.
