<strong>Step 10:</strong> Zoom into the bottom of the egg and perform the same operation on the connection between the spline and the 6mm line. Again, the goal is to make the spline approximately horizontal where it connects with the 6mm line to maintain the continuity of the curve. As you manipulate the spline, you might like to click on the Show Curvature checkbox in the left column to see a visual representation of the intensity of the spline's curve at each point. Change the curvature scale and density to taste.

<strong>Step 16:</strong> You should now have a 3D egg similar to the screenshot below. However, this design is not ready for 3D printing. You can click and hold the scroll wheel to rotate the egg, and you'll notice that the 6mm line at the bottom of the egg has now turned into a 12mm diameter circle. We have intentionally made this flat spot a little larger to get better adhesion to the base plate during the print, but it is not sufficient on its own to keep the egg from tipping over in the event that the nozzle crashes into it. Later on, we will add supports to the bottom part of the egg using the Prusa 3D Slicer software that will support the shallow parts of the egg's curvature. But for now, we are going to add structural supports in SolidWorks that will mitigate the risk of the egg tipping over in the middle of the print.
