I would first go to any town that doesn't have 3d printing going on. Then find someone who is willing and dedicated enough to sit and learn how to use it. I would want to find someone that can start 3d printing movement in their town. I will say I have a lot of people around me that I would like to give one to, but I'm afraid it will get shelved. It will either be due to laziness or because they will get frustrated with the machine and push it away. You need someone who is creative, first off. Someone willing to push through the problems and achieve their goals.
