In this chapter, we're going to use at a 3D CAD program called SketchUp Make. What makes this program different from most CAD programs is the ease of its use. SketchUp is not a parametric modeler such as AutoCAD or Solidworks. It doesn't require heavy training and a lot of investment in money. It's an easy, intuitive modeler that allows for direct interaction with the geometry. This provides greater flexibility in making a model on the spur of a moment when creativity sparks.

Later in this chapter, we'll learn how to calibrate the mechanics of our printing by making some changes in the motion of the printer. We'll also examine a variety of solutions for controlling print warping. Controlling warping of prints made with ABS is a very common issue. We'll take a look at different solutions for this problematic issue.
