Hinges are big part of the three-dimensional (3D) designs. They improve mobility of the parts that are connected by it through angular rotation. For example: a door, a house-hold furniture, the folding mechanism of a laptop etc.
In this module, we learn how to create a hinge for 3D printing. Here's a video that demonstrates this.
