3D designing a Computer Mouse in a 3D Modeling Software

 |  Devyani Nagare

Whether you are just getting started in 3D designing and are just playing around with 3D modeling software like SelfCAD to see what you can come up with or you are a professional who has been in the 3D modeling industry for some time now, we’re going to show you how you can create a model of a mouse in SelfCAD. 3D designing has applications in many areas, and one of them is prototyping. In this article, we are going to learn how to 3D design a prototype of a computer mouse using 3D modeling software.

For beginners, to learn how to use a 3D modeling software or any other tool, you need to learn by doing and that’s why we’ve prepared this tutorial to help you learn how to use SelfCAD. SelfCAD is one of the easy-to-use beginner-friendly 3D design software out there.

As you learn how to 3D design the mouse, you will also get to know how to use some important tools of SelfCAD like the Bend tool. You will also learn to bend with your desired sharpness and smoothness. Also, there are many other tools like polygon, fillet, etc., that you will learn. So keep reading!

Step‌ ‌1:‌ ‌Create‌ ‌Object‌ ‌

We‌ ‌will‌ ‌start‌ by ‌creating‌ ‌new‌ ‌objects.‌ ‌First,‌ ‌we‌ ‌will‌ ‌activate‌ ‌the‌ cube.‌ ‌‌Select‌ ‌the‌ cube ‌from‌ ‌the‌ ‌3D‌ ‌shape‌ ‌category‌ ‌or‌ ‌use‌ the ‌shortcut‌ ‌(P+C).‌ 

Add the parameters according to requirement. So set width to 150, height to 10, width segment to 20, and depth segment to 20. Finalize the Cube.

Click to activate the Polygon Selection or use the shortcut (Ctrl+4). Click on the highlighted region to select it. 

Step‌ ‌2:‌ ‌Activate Inflate ‌

From the Deform Category of the toolbar, choose Inflate or use the shortcut (D+I). Next, we will make the region inflated. Set y to 27 with the highlighted gizmo.

Step‌ ‌3:‌ ‌Activate Bend ‌

Activate the Bend. From the Deform Category of the toolbar, choose Bend or use the shortcut (D+B). Set x to -43 and close the Transformation Panel. 

So we have made the front bend to give it the shape of a mouse.

Step‌ ‌4:‌ ‌Create‌ ‌Object‌ ‌

Select‌ ‌the‌ cube ‌from‌ ‌the‌ ‌3D‌ ‌shape‌ ‌category‌ ‌or‌ ‌use‌ the ‌shortcut‌ ‌(P+C).‌ 

Set the parameters according to requirements. So set Width to 150, Height and Depth to 100. Finalize the Cube.

We will activate the Edge Selection. Click to activate the Edge Selection or use the shortcut (Ctrl+2). Next, click on the Highlighted region to select it. 

‌Step‌ ‌5:‌ ‌Activate Fillet

From the Modify category of the toolbar, choose Fillet or use the shortcut (M+F). Set the Intensity to 40, and Level to 10. Now, we have basically smoothened the edges of the created shape.

Finalize the Fillet.

Activate the Object Selection: Next, click on the Highlighted region of the cube or use the shortcut (Ctrl+0) to turn off the region selection. Click on mesh_4 to select it. 

Step‌ ‌6:‌ Activate Stitch & Scoop.  ‌

Choose the Stitch & Scoop tool from the toolbar or use the shortcut (B). In the Tool Panel, choose Intersection or use the shortcut (B+I). Finalize the Intersection. We created this shape using Stitch & Scoop.

Step 7: Activate the Flip and Create Object

Now, from the Utilities Category, choose Flip Normals or use the shortcut (U+F). 

From the 3D shape category of the toolbar, choose cylinder or use the shortcut (P+Y). Set the parameters according to requirements. Set the top radius to 10, and the bottom radius to 10 as well. Height to 8, Position X to -50, and Rotation X to 90. Finalize the Cylinder.

Next, click the intersection_1 to select it. Activate Stitch & Scoop. Choose the Stitch & Scoop tool from the toolbar or use the shortcut (B). In the Tool Panel, choose Difference. Next, choose mesh_12 to subtract and set the subtracted parameter to True. Finalize the Difference.

Next, click the difference_1 to deselect it. Activate Polygon Selection or use the shortcut (Ctrl+4). Click on the Highlighted region to select it. 

Click on Activate Edge Selection or use the shortcut (Ctrl+2).

Step 8: Activate Fillet

From the Modify category of the toolbar, choose Fillet or use the shortcut (M+F). Set the Intensity to 3, and Level to 5. Finalize the Fillet.

Click to activate Polygon Selection or use the shortcut (Ctrl+4). Click on the Highlighted region of the cube, or use the shortcut (Ctrl+0) to turn off the region selection.  Click on difference_1 to select it. Click on mesh_12 to deselect it. Activate Polygon Selection or use the shortcut (Ctrl+4). Click on the Highlighted region of the cube, or use the shortcut (Ctrl+0).

Click the Copy button or use the shortcut (Ctrl+C). 

Step 9: Activate the Add Thickness. 

Choose Add Thickness from the Modify Category of the Toolbar, or use the shortcut (M+A). Set Parameters as follows: Set Thickness to -1 and finalize the Add Thickness.

Now you can color the Mouse. 

Conclusion:

3D designing a mouse using 3D modeling software is as simple as described above. Though there are many other methods and techniques that can be used in creating mouse prototypes, 3D modeling is one of the easiest methods that you can use. 

After the 3D design process, you can then 3D print your design by slicing it using the in-built slicer of SelfCAD software.


Enjoy powerful modeling, rendering, and 3D printing tools without the steep learning curve.
