How to 3D Design Airpods in SelfCAD 


3D designing offers unlimited opportunities; the more you experiment, the more you get to create designs of different kinds. 

In this tutorial, we are going to use Mirror, Stitch and Scoop, Polygon Selection, Object Selection, and many other tools of SelfCAD to 3D design AirPods. 

The tutorial starts with a Sphere Object and is then modified with the help of the Move tool. The Solid+Wireframe rendering helps us to show the structure lines of the object. With Solid+Wireframe, we can select only a specific region of an object in combination with polygon selection. Next, we also color it. 

The mirror tool makes our work more manageable when we need to design the exact object, but in reflection, we also have a copy tool, if we want the same design without reflection. 

Mirror tools save time. 

Next, with the Cube shape, we will create the Earbud case. Starting from designing the cube shape, we split the top cover to give it the look of an open case. We have also used the Add thickness tool. Whenever we select the 3D-Objects, they are hollow from the inside. When we split and open the cube, it will be hollow too. The outer cover is not thick enough to give us a good look. The Add thickness tool helps us to add the thickness to the edges of the 3D design. 

There are various AirPods designs, from big to compact. 3D Modeling helps create various designs used nowadays; even one of the perfect designs may be plugged in your ear right now. 

Below are the steps to help you learn how to 3D design AirPods in SelfCAD.

Let’s get cracking!

Step 1: 3D Design the Sphere Shape for Earbud

We’ll start with creating an object that is a Sphere. Select the Sphere from the 3D shape category (P+S). 

3D designing a Sphere

This is what we get after selecting the Sphere Shape. We can modify it in various ways; that is what we do in 3D-Designing. After activating the Sphere Object, the parameter panel appears, including Radius, Horizontal Segments, Vertical Segments, and Arc. Other than these tools, the parameters also consist of Position and Rotation used to display the object to finalize the Position and Rotation. 

Now, Set Position to X to 100, Position Y to 200, Rotation Z to 90.

Finalize the Sphere. 

Finalizing the 3D design of Sphere

Now select the Solid+Wireframe to set the rendering mode (V+C) as shown below.

Wireframe mode

Select wireframe mode

The Solid+Wireframe shows the 3D design in its structure. Other options will show us just Solid, Wireframe, Smooth Object, and No Culling. Following is the Wireframe Structure that we can see. 

The 3D design in Wireframe Mode

 Below, you can see the structure of the 3D design that is visible after activation of the No Culling tool.

For Now, we are using the Solid+Wireframe tool. 

Step 2: Modifying Sphere 

Let’s now manipulate the sphere. Choose the Polygon Selection or use a shortcut (Ctrl+4). Select the Region as shown in the 3D design below.

Modifying the Sphere

Choose the Move on the Toolbar and set y to 92.43.

Modifying the Sphere

Click Object Selection, select the section from a cube, this will turn off the region selection. Activate Polygon Selection (Ctrl+4) and Select the Region.

Selecting the regions of the 3D design

Set z to 59.8. 

Setting the parameters of the selection

So here we use the Move tool to move the structure line and create the structure we want. Move tool makes it easy to modify the structure of the 3D design without keeping in fault or extra structure. So this is where the Solid+Wireframe structure will help us identify the structure line more properly and modify the shape. 

Step 3: Smoothening the Earbud and Coloring it. 

Let’s now perfect and color the earbud. Select the Round Object and select smoothness to 2. The maximum smoothness is 5, and the minimum is 1. 

The following shows the smoothness at 1.

The 3D design below shows smoothness at 4 and 5, respectively, but in solid mode.

Finalize the Round Object of the 3D design.

Now we will color the object first. Click on Color Picker and choose Apricot color, and then the Ok button to confirm the color.

Okay, the 3D design above looks a bit off, but why?? It’s because our solid+wireframe mode is still on. So, select the solid button to set the rendering mode or use a shortcut (V+S).

The 3D design below is what we get. 

Selecting solid option

Step 4: Colouring other parts of the earbud. 

Activate Polygon Selection (Ctrl+4). This will select the region that we need to color. 

Coloring other parts of the airpods

Select the Color picker button to choose the color. Next, click on the custom button to select the perfect shade that we need. Here, type #f85a5a into the color picker input. Click on the Ok button to confirm the color. Next, deselect the region we selected with the polygon selection tool of the selecting mode.

It’s not dull anymore, right?

Step 5: Mirroring the Airpod. 

Now we will create a copy of the earbud. Click Object Selection, select the section from a cube (Ctrl+0), this will turn off the region selection. 

Activate the mirror: From the toolbar, choose the Utilities and select the Mirror. In the tool, the panel Creates a copy to True. Set Offset to 10. Finalize the Mirror. 

Mirroring the airpods

So we have created a copy of the first created Earbud. This is the reason that we have already colored so we can copy the colors too. Also, the Offset in the mirror is the distance at which we want our object. We chose Mirror because we wanted the other object to be a reflection of it, so it looks like they both are facing each other.

Step 6: Creating the Airpod Case. 

It’s time to 3D design the Airpod case! From the 3D shape category from the toolbar, choose the Cube (P+C). 

Set the Width to 125, Height to 270, Depth to 274, Position X to 100, Position Y to 66, Position Z to 78. 

Finalize the Cube. 

Creating a cube

Activate Fillet. From the Modify category of the toolbar, choose the Fillet tool (M+F). Set Intensity to 38, level to 7. Finalize the Fillet. 

Modifying the cube using Fillet tool

Click on Isolate to Isolate the selected object (V+I).

Isolating the selected objects

Activate Object Selection. Click the parts from the selection cube (Ctrl+0) to turn off the region selection. Set Bottom to 210. Finalize the Cube selection. 

Selecting using Object selection tool

The case is ready!

Step 7: Split the Case top. 

Next, we will split the object to open it up to show it as a case. So click on the Utilities category from the toolbar and choose the Split or use shortcut (U+S).

Splitting the selected top section

We’ve created the lid; however, we can’t see it. It is visible in the right tool panel, and it shows as two separate objects. Now we will position the case cover. Click on Rotate from the toolbar (R). Set Origin Layer to Bottom and origin position to Right. These options are available in advanced settings. 

 Set Z to 130 and close the Transformation Panel. This is the perfect look that we get.

Isn’t it perfect? Wait! We aren’t done yet. Let’s move on to the grooming part!

Step 8: Adding thickness to the case. 

Next, we will Add Thickness. Choose Add Thickness Tool (M+A). Set the Thickness to 3 and Finalize the Add Thickness. 

Adding thickness to the Case top

So we added the thickness to the case of Top.

So we filled the Case. 

Now select both the earbud; click on mesh_4(1) and mesh_4 to select it. Activate the Stitch & Scoop tool or use shortcut (B). In the tool, the panel chooses Difference or uses a shortcut (B+D). Here choose the mesh_4(1) and mesh_4 in the subtracted object and set keep subtracted object to True. Finalize the Difference.

Choosing mesh option


Choosing the stitch and scoop tool

So with Stitch and Scoop, we can create or separate cases from earbuds. You can see in the above 3 designs- two images before and after stitch and scoop. 

Step 9: Set the Earbuds properly. 

Let’s arrange the earbuds in the case. Activate Move. Select Move on the Toolbar or use a shortcut (M). Click on difference-1 to deselect the object. As other earbuds are already selected, we will move them and set y to 396.4. Close the Transformation panel.

Step 10: Colouring the Airpod Case. 

Last but not least, let’s color the case. We will select the objects: Click on mesh_9, difference-1 to select it.  Click mesh_4 and mesh_4(1) to deselect it. So this is the case. Now we will color the object. Click on the Color picker and choose the custom to select the needed shade of color. In custom type #F85a5a value into the input. The value is shade color. Click on the Ok button to confirm the selected object.
