In this 3D unit, I designed a case for my earplugs. The case is composed of 1 upper component and one lower component, connecting by the hinge. A cuboid and two hinges form the upper part. I rounded the cuboid to make the case more smooth. The two hinges are attachable, so I can print the upper and lower components separately and attach them after the printing process. I used two cylinders to form the hinges; the bigger one is cut by the small one. A cuboid and two cylinders form the lower body. The cuboid was also rounded. For the connecting joint, I used two rectangles to create space for the hinges, and I sketched and extruded two circles, which formed two cylinders. These cylinders are crucial for my case as the hinges revoluted on them.
I’m proud of the design of the hinge in my features of the model. The hinge is attachable, which is a great idea to increase the lifetime of the product. For typical cases, if the case doesn’t revolute, you will have to buy an entirely new case. However, if the upper component is broken in my model, I will only need to replace it and print another case because it’s attachable. One thing that challenged me is to learn and used new features in fusion 360. Due to my lack of experience in 3d modeling, it was hard at first to get familiar with different tools. I overcame this problem by searching for additional materials online and seeking help from my teacher Mr.Beatty. After finishing this unit, I gained tons of experience using these tools such as sketch, joint, and clearance.
