APSC 162 is an engineering graphics course and covers how to create engineering drawings by hand. The course also serves as an introduction to Solidworks. Our final project for the course was to design a speaker that could be sold as a product. We were provided with CAD files of two speaker drivers (one big, one small) and a PCB, and were given material mass constraints that our design had to be under. This project was a great opportunity to exercise my knowledge of CAD design and engineering drawing conventions. 

Final Design 

The intent for the design was to use an ABS mould to get the desired speaker man shape, and have cutouts for each driver so it could be fit in with an adhesive mold. Below shows the principal views of the assembly.

Here are the drawings for each part that I designed, as well as an exploded view of the assembly.

Takeaways

Exploded Views and Detailed CADs are crucial - In order to validate that what is designed can actually be put together, it is super important to put a lot of effort into CAD models and ensure that every part of an assembly is present in the model. This way, there are no surprises when things are being put together. Also, exploded views can be a good way to visualize if your project is assembleable.
