Derby the dog has a birth defect that renders his front legs mostly useless. After his original owners surrendered him, animal-rescue organization Peace and Paws took him in, and that’s where he caught the attention of Tara Anderson.

Anderson is the director of CJP product management for 3D Systems, a company that specializes in 3-D printing and prototyping, and when a cart didn’t work well enough for the dog’s needs, Derby received some custom-made, 3D-printed prosthetics. The team decided that spring-like “running man” limbs would get stuck in the ground, so Derby’s new legs are rounded for maximum mobility and comfort.

Tortoises are born with houses on their backs. But what if their legs aren’t strong enough to move about with such a burden?

A veterinarian in Germany found a solution for one gimpy tortoise by raiding his son’s toy collection: Dr. Carsten Plischke used Lego bricks to make a kind of scooter for Blade, a shellback that has difficulties walking because of a growth disorder.
