This is a lesson plan for an educational activity involving 3D printing and Arduino technology. Here's a breakdown of the content: **Introduction** The lesson involves creating a 3D printed case for an Arduino Uno board using a 3D printer and slicing software like Cura. The model is designed to showcase the capabilities of 3D printing, including its limitations. **Objectives** 1. To understand the basics of 3D printing and layer-by-layer construction. 2. To explore the limitations of consumer-level 3D printing compared to CNC cutting/milling/lathe machines or molded plastics. 3. To demonstrate how technology allows prototyping and design for a minimal investment and footprint. **Materials Needed** 1. Arduino Uno board 2. 3D printer with filament (PLA is recommended) 3. Optional: 123D Design software, Raspberry Pi 3, MeshMixer, Cura slicer software, LED, and resistor **Procedure** 1. Print the model using a 3D printer. 2. Experiment with different component print settings and speeds to achieve optimal results. 3. Discuss the limitations of consumer-level 3D printing and how it compares to other manufacturing methods. 4. Introduce slicing software like Cura and show students how to visualize the tool paths and layers that produce the part. 5. Have students upload an Arduino sketch to the board and run it on the board, watching the LED blink. **Tips and Variations** 1. Encourage students to experiment with different colors or customization to provide visual distinction between projects. 2. Suggest using Cura's LAYERS view to visualize the tool paths and layers that produce the part. 3. Discuss how social media platforms like Thingiverse allow sharing of ideas, products, and cooperative work models. **Duration and Preparation** The lesson plan suggests a duration of 30 minutes to several days, depending on the complexity of the project. The preparation involves installing software, setting up the 3D printer, and having Arduino boards and components ready for use.
