Chapters 4 through 7 covered a lot of information about how to create a 3D model, slice it, and print it in your chosen material. But it was a lot of information, so now we will walk through a few different case studies to show you how to think about particular design problems, how to make an object as simple to print as possible, and how to anticipate issues you may have to deal with during the print. The material in this chapter to a degree duplicates the material in Chapters 4 through 7. We don’t explicitly refer back to those chapters by and large, but we apply that material here and in some cases expand upon it a bit for a particular case. The goal of this chapter is to give you some intuition about good practices so that you can over time learn all the details without being overwhelmed.
