Is there any cute animal 3D printing can’t save? Just look at TurboRoo, a tiny Chihuahua born without front legs, who has been given a new “leash” on life thanks to a Makerbot and a 3D designer from 3dyn. Mark Deadrick, president of 3dyn, saw TurboRoo’s call for wheels on the Internet and designed a small wheeled cart, estimating the size from online photos. He printed the model in bright orange, slapped on some Rollerblade wheels, and sent the cart to TurboRoo’s owner. Now the wee doggie is scooting along on a free, fully hackable set of super-legs. Why is this cool? Because, before 3D printing, TurboRoo’s owners would have had to build something out of ready-made pipes, cloth, and other materials at great cost. Now, however, the cart can be custom-fit to TR’s body, reprinted at will, and even modified by other designers.
