Lab 10: 3D Modeling

Professor: Marcela

Partner: None

Material: Tinkercad, a 4 digit display

In previous lectures, we have already leared how to use Tinkercad to create models for 3D printing. Today, we were required to use Tinkercad to design a 3D model of a wearable device, a game controller or a security camera that can support some of the sensors. And I decided to design a watch. I would draw the watchband and the container supporting  a 4 digit display (which is the dial plate) with Thinkercad.

I first create a solid cylinder with radius of 30mm and with height of 9 mm. In order to make a watchband, I inserted another hollow cylinder. However, these two clinder can not fit with each other very well, since I change rotated one of them. I deleted the original  hollow clinder and copied the solid cylinder to make these two models combine with each other. For the container for the 4 digit diplay, I created a half-cylinder. Before I made the model, I measured the size of the display with a venier caliper. I set the length of the display as the height of the half-cylinder, and the width of the display as the diameter of the bottom circle of the half-cylinder. In this way, cables connected with the  4 digit display woule be attched to the inner side of the the watchband and people can check the time with the diplay contained by the half-cylinde. Here are some pictures about the watch observed from different angles.

Through today’s lab, I became more familiar with Tinkercad and 3D printing. It is beneficial for me to  put it into practial project and use it in my lives.
