Summary

In your grandparents' or parents' garage, they might have had a jigsaw and tools that they made cute wooden puzzles with—clunky shapes that vaguely resembled an elephant or truck. But nowadays, we can do so much more with 3D printing. It's not difficult to see how this project can be applied to a puzzle of any shape, just as complex or robust as a loved one's favorite thing:

Blender's unique collection of tools seems eclectic to some, but in the end, they enable robust interactions that result in us being able to make projects such as this puzzle without having to switch tools to finish. Models can be sculpted and then, without switching tools, combined with rigid shapes to create complex but useful and fun objects for 3D printing. This project also taught you about tolerances in 3D-printed parts and how they can be adjusted to make parts that interact with each other. While different 3D printers may require different tolerances, the skills learned in this chapter can be applied to...
