Odd Egg

thingiverse

This intriguing model showcases a paradoxical phenomenon where the centroid of geometric form and the center of mass are not aligned. Printer Settings Printer: Rafts: No Supports: No Resolution: 0.2 Infill: 100% Notes: This object features a flat base for easy printing on the bed, eliminating the need for rafts or supports. The STL file was created in AUTODESK INVENTOR and should be scaled down to 1/10 for optimal printing results. How I Designed This Step I Create an ellipse and transform it into an egg-like shape. The dimensions of this ellipse are crucial... Step II Divide the object at a slanted angle. Step III Develop a shell around the egg. Step VI Add a flat base to ensure easy printing. Custom Section Objectives This design focuses on the concept of mass center and geometry centroid. In school, simplified math models are often used to solve problems, but real-world scenarios demand more attention to detail. I hope this model helps students better understand the concept it illustrates. Audiences Middle school to high school students with basic INVENTOR skills can create this design. Preparation A 3D printer and a computer with CAD software, such as INVENTOR, are required. Steps This model demonstrates the concept of a center, which can be applied to various shapes, like an egg, ball, or cube. Refer to the step-by-step tutorial in the previous section for detailed instructions. All steps took only 10 minutes to complete, and I believe students with basic CAD skills can draw this model quickly.
