To learn how to use my 3D Printer I undertook a project to create a custom PC case. I chose this project as I found the current PC housing that I was using to be sub-optimal and was not truly utilizing the volume well.
To remedy this, I took measurements of my parts and began using Fusion 360 to model the entirety of the chassis that the parts would sit in.
This was a 6 month long journey filled with multiple reprints, molten parts and a lot of starting from scratch, but it ended with a complete chassis that withheld the heat that the system put out and was modular and upgradable.
