Happy CADing-Design Earbuds with ZW3D

Remus Pacis, a mechanical designer and application engineer of different platforms, has over 10 years’ experience in product design. He is also an application engineer of different platforms, skilled with ZW3D at product design, mold design, and manufacturing. He’s been doing different product design for local clients and freelancing groups. He also actively joined different global design contests and won the 1st place for the last 3 consecutive design contests of ZW3D.

In this article, he will share some of his design experience with ZW3D by demonstrating a specific model design – earbud. Here we go!

Doing this design is not as simple as it looks, but the handy commands in ZW3D made my design work easier.

Figure 1. Wireless Earbuds Design

First of all, I created a sketch to control the X and Y dimensions of the earbud.

Then I created a sketch for the side of the shape. I used Sweep command to form the sketch along the side curve of the extruded part.

For the extended part of the earbud, I created 3D curves firstly, then used N-sided to patch the part.

Next, I combined the well-defined sketches and used the Revolve command to generate the soft part of the earbud.

With the powerful Fillet command of ZW3D, I was able to create a variable surface fillet. I firstly made over the extended surface then trimmed it using the side wall.

For additional details of the earbud, I extruded the sketches to create several shapes which I used to divide the main body. ZW3D is very useful when working on projects with multiple shapes.

Morphing command really saved my time in designing the volume button, which I needed to wrap along the side of the product.

It’s the same to design other details with the Morphing command.

After that, I used the Fillet command to give finishing touches on the volume control.

Then, to get an identical one for the other ear, I used Mirror command to duplicate the parts and then used Extract command to convert each part into a component. To this point, the design of the earbuds was almost done.

Finally, I rendered the models in the style I like to finish the design of the earbud.
