Summary
Now you have a good idea of how to use the Ruler/Protractor tool and how to unwrap a UV map, paint a texture map, and apply it to the object. You also learned how to use the F Clone brush to create a texture that is more detailed than you would want to do with the Blender painting system.
In the next chapter you will be introduced to what it takes to properly make a Blender model for 3D printing. You will learn how to measure it precisely and how to make the object so it will come out correctly into the real world.
