Outer Casing for Strawberry Pie Circuit

The main purpose of this design is to create a protective and well-structured case that houses the electronic components safely while maintaining accessibility to ports and connections.

The enclosure is designed with attention to size, shape, and functionality, ensuring proper fitting of the board and ease of assembly. In addition, the design considers aesthetic aspects by providing a clean and modern appearance.

This project demonstrates the integration of mechanical design with electronic systems, highlighting the importance of 3D modeling and assembly techniques in real-world engineering applications

First, I downloaded the circuit from a website called GRABCAD; I will include the link at the end of the report. After downloading it, I imported it into Fusion 360, as shown in the image below.

Step 2: Designing the Base

The next step was creating the base for the circuit. I sketched a rectangle and applied an Extrude command with a thickness of 1.5 mm. Initially, I used the exact dimensions of the circuit (91 x 57 mm), but I later adjusted them after realizing that some components were protruding beyond the base. To avoid this issue, it is always recommended to include an offset or extra margin in the dimensions.

Step 3: Component Conversion and Assembly Following the base design, I converted the base body into a Component. This is a crucial step that must not be overlooked, as it is a prerequisite for any Joint operation. Once converted, I applied the Joint command to accurately assemble and secure the circuit onto the base

In the next step, I performed another Extrude operation on the base, followed by applying a Fillet command to the edges. This was done to round off the sharp corners, ensuring a smoother finish and a more professional appearance, as shown in the image

Step 5: Creating a Reference Plane

Finally, I defined the center of the structure using the Midplane feature (located under the Construct menu). This allowed me to establish a reference plane exactly in the middle of the model, which was necessary to identify the exact face where the body would be split into two symmetrical halves

"After that, I used the 'Split Body' tool. I selected the body and used the midplane created earlier as the splitting tool. This successfully divided the box into two separate halves, as clearly shown in the image.

In this step, it is essential to incorporate all the openings and holes present in the circuit design, as illustrated in the image. Ensuring these slots are accurately placed is vital for the proper fit and functionality of the final model

In this step, I created all the necessary mounting holes based on the circuit's dimensions. I added a 0.2 mm clearance (tolerance) to each hole to ensure that the circuit can be easily and securely fastened to the base using screws, as shown in the IMAGE

In the final step, I added a custom logo to the circuit box. I used an SVG file and performed an 'Insert SVG' command into the program. The logo was then positioned on the top face and extruded to create a clean, professional finish. With this step, the design is complete after adding some color .
