I am so sorry to hear of Andy's passing. He and I were always cooking up big plans for 3D printing anatomical models and other adventures. We had a list going. He had tremendous patience with students (and faculty) and was so generous with his time and knowledge. No request was too much. I feel I have lost someone with whom I had a true meeting of the minds. My condolences to Andy's mom and the whole family. He touched so many lives in a positive way.
