I got my first 3D printer, a Creality Ender 5, during the pandemic, which led me to learn CAD, Raspberry Pi, Arduino, and many more skills through YouTube. I upgraded it with a direct-drive hotend, added OctoPrint for monitoring, and installed a BL Touch for auto bed leveling, troubleshooting firmware and hardware issues along the way. I also worked on my printer’s motherboard and other electronics. Since then, I’ve upgraded my 3D printing setup and created projects that pushed me to become a better engineer.
