Model a custom Raspberry Pi 5 case | Modeling projects

Introduction

In this tutorial, you will learn how to design a custom case for the Raspberry Pi 5 using Shapr3D. Mechanical Engineer Gabe Corbett guides you through various tools and techniques available in Shapr3D, allowing you to create a functional and manufacturable case. This step-by-step guide will cover importing reference geometry, sketching essential features, and finalizing your design.

Step 1: Import the Raspberry Pi 5 Model

To start your design, you need to import the Raspberry Pi 5 model into Shapr3D.

• Open Shapr3D on your device.
• Navigate to the import feature.
• Select and import the STEP file of the Raspberry Pi 5. This will serve as a reference for your design.

Step 2: Use Sketch Tools to Create Features

Once your Raspberry Pi model is imported, utilize sketch tools to create important features of the case.

• Select the Circle tool to create mounting bosses.
• Use the Rectangle tool to design port cutouts.
• Sketch additional necessary features based on the Raspberry Pi’s layout.

Step 3: Offset Edges for Accurate Boundaries

To ensure precise boundaries around your imported geometry:

• Select the Offset Edges tool.
• Click on the edges of the Raspberry Pi model to define the case features accurately.
• Adjust the offset distance based on your design requirements.

Step 4: Build Case Walls with Extrude Tool

Next, you will construct the walls of your case using the Extrude tool.

• Select the profile of the case that you want to extrude.
• Use the Extrude tool to set the wall thickness and create parameter-driven extrusions.
• Ensure the dimensions match your requirements for functionality and aesthetics.

Step 5: Combine Parts with Boolean Operations

To refine your design further, use Boolean operations to combine or subtract parts.

• Use the Union operation to merge multiple components of the case.
• Apply the Subtract operation to create cutouts for ports and connectors, ensuring they align correctly with the Raspberry Pi model.

Step 6: Finalize Your Design with Visualization

The last step is to enhance the presentation of your case design.

• Apply materials and colors to different parts of your case using the visualization tools in Shapr3D.
• Review your design for any necessary adjustments and ensure everything is in place.

Conclusion

You have now completed your custom Raspberry Pi 5 case design using Shapr3D. By following these steps—importing the model, sketching features, creating walls, using Boolean operations, and finalizing with visualization—you can produce a precise and functional case. As a next step, consider exporting your design for 3D printing or further refinement. Happy designing!
