The final project in my Solidworks CAD course was designing a 20:1 gearbox. At the time my team and I had very little exposure to the engineering world. This was our first time searching for parts like bearings online. After many hours on McMaster and MSC we finally found all the parts we needed to manufacture a gearbox that would fulfil the design requirements. The lessons I learned while working on this project guided much of my future mechanical design decisions.
