If you have the desire but not the time, you could sell the model through Shapeways. They would take care of the shipping, money and printing for you and you would just have to answer questions and accept the money. They would also let people buy different price points of the model in different materials all for no work for you. True, they would take a chunk out of those profits but if the choice is them doing all the work or you losing a chance to earn some money for your school, it's a viable option.
