Derby the dog was born disabled, with deformed front legs that severely restricted his mobility. When Tara Anderson met Derby, rather than just pity him, she decided to do something about the situation.

This lead to Idea 2.0: Having access to 3D modelling software and 3D printing equipment allowed Tara and her coworkers to make custom prosthetics that... Well, you have to see for yourself.
