Tazo’s Triumph: A 3D‑Printed Prosthetic Cart Restores Mobility to a Paralysed Dog

Meet Tazo

Tazo was born with a severe back‑leg injury that left him unable to use his hind limbs. In the spring of 2015, his former owners were unable to provide the care he needed and he was taken in by Animal Haven, a New York City shelter dedicated to helping animals in need.

Turbo Roo Designs to the Rescue

Turbo Roo Designs, renowned for creating innovative prosthetics for dogs, learned of Tazo’s plight. The team had already engineered front‑wheel carts for their signature Chihuahua, TurboRoo, but this was their first attempt at a back‑axle design. Their initial prototype—a metal frame with concentric bars and heavy hardware—proved functional but far from optimal.

Creating the World’s First 3D‑Printed Back‑Wheel Dog Cart

Seeking a lighter, more elegant solution, Turbo Roo partnered with Justin Finesilver from the 3D Printing Store. Together they designed a custom cart in SolidWorks, using precise measurements from Turbo Roo. The parts were printed on a MarkForged machine with 10% nylon infill—no composite reinforcement needed—because nylon’s strength and flexibility matched the cart’s requirements.

After printing, the nylon components were spray‑painted and assembled. Justin notes, “This cart represents a significant upgrade in weight, functionality, and style.”

Transformation and Adoption

Within minutes of Tazo’s first trial, he wagged his tail and seemed to feel the freedom he had been missing. The new cart turned his difficult spring into a vibrant summer, and he was adopted shortly thereafter, thanks in part to the buzz around his story.
