Third day at 3-D printing camp, half way done with this week, and still enjoying learning new things. There was a continual development of skills previously learned on Tinker-cad, and use of these skills in new projects and lessons. One such project was a castle which tested the knowledge gained from previous days about structural integrity. It was a new and exciting challenge to design a unique building from scratch. It gives a lot of new insight into architectural design and challenges of building.
