Fusion 360: Designing the Console

Creating the Console

1. Sketch: Create a new sketch on the Top Plane.
2. Rectangle: Draw a Center Rectangle from the origin: 95mm x 85mm
3. Extrude: Press E and extrude it upward by 60mm.
4. Fillet: Press F. Select the four vertical corner edges and give them a 10mm radius to make it handheld-friendly.

Creating The Spaces for Future Buttons and Screens

1. Sketch on Top Face: Select the top surface of your block and create a new sketch.
2. LCD Window: Draw a Center Rectangle near the top half: 72mm x 25mm (this is the visible area of a 1602 LCD).
3. Button Holes: Draw two circles (diameter 7mm) below the LCD window where you want your "Advance" buttons to sit.
4. Extrude Cut: Press E, select the rectangle and circles, and extrude downward by -5mm (this creates the indentations for your cast).

Create the Interior Cavity (The "Void")

1. Shell Command: Go to Modify > Shell.
2. Select the BOTTOM face of the block.
3. Inside Thickness: Set to 3mm. This hollows out the inside so your electronics have a home.

Create a Half-Scale Model for Prototype Testing

1. Right-click the body in the browser tree and select "Create Components from Bodies".
2. Right-click component from the browser tree.
3. Select "Copy".
4. Deselect components by clicking outside the browser tree in the workspace of Fusion.
5. Right-click the workspace of Fusion.
6. Select "Paste New".
7. The Move arrows will come up, move the second component away from the original



8. Go to Modify > Scale.
9. Selection: Click on the second console body (or select it from the browser on the left).
10. Point: Select a corner of the model or the center origin. This is the "anchor" point it will shrink toward.
11. Scale Type: Ensure this is set to Uniform.
12. Scale Factor: Type 0.5.



13. Click OK.

Export for Printing

1. In the Browser on the left, right-click your Component or Body.
2. Select Save as Mesh (or Export > STL).
3. Set Refinement to High.
4. Open in your slicer (PrusaSlicer) and start the print!
