Black + Decker Cordless Drill Teardown
For this project, I chose to model a lot of small interior components of the drill. This project was highly enjoyable and I learned how to efficiently model pieces, a variety of ways to approach modeling, and what approaches suit me best. All pieces were designed in SolidWorks.

Modeling a variety of interior pieces meant that I made many simple pieces and a number of slightly more complex pieces. To the left are some of my favorites that I modeled.
I really enjoy figuring out how to approach different problems, and modeling so many different pieces gave me a lot of problems to think about.
On the top left is the bit holder, which I picked to include in my favorites because I enjoyed making the angled holes in the larger piece and constraining the assembly so the pieces move in and out as they do in the drill. I also picked the bit to include because I enjoyed making the Phillip's head and it fit with the bit holder.
I included some of the caps I made because I think the detail you can get from basic extrudes and cuts is incredible, and I also got better at adding threads to different items.
For this project, we also made a product decomposition table, and recorded our disassembly process. You can download the pdf here.
