In this 2-part lesson, students will design and 3D print their own castle model. During the lesson, they will experiment with demonstration models and make design decisions on how they intend to improve the design and aesthetics of the demonstration models. In the main part of the lesson, students will follow an instructional video to design a castle comprised of common 3D shapes. Using the skills learned in the tutorial, they go on to design their own unique castle model.
