Jason and Dori Walker live in California with their eight children. Their adopted 14-year-old daughter, Layla, is blind so Jason has developed a unique method of introducing her to new things. Dori and Layla both state that her hands act as her eyes so Jason acquired a ROBO 3D printer to help his daughter learn. Now the family print everything from a cupcake to the state of California so Layla can experience their appearance first-hand. Credit: YouTube/ROBO 3D
