#  Catapult Design Project

Catapults were destructive siege engines in medieval times. In this project, you design and fabricate a model catapult to learn the basics of CAD and 3D printing. These projects include documents, videos, and step-by-step instructions.

- **Grade:** 9-12
- **Length:** 4-6 hours
- **Difficulty:** Moderate
- **Software:** SOLIDWORKS xDesign (though SOLIDWORKS 3D CAD can also be used)
- **Learning Objectives:** Understand different types of catapults. Design with constraints by applying design intent to the project. Explore and understand manufacturing principles. Understand the basics of 3D printing.
- **Materials Needed:** Filament (approximately 70g), 1 package of #2 size rubber bands, 1 package of (30) 7/8" diameter foam balls
