For their project in ENME444 Mechanical Engineering Systems Design, a team of 5 students (aka Team Geezer), designed and built a computer numerical controlled (CNC) mill that any student could build and use for their undergraduate projects. They received support from and posted their completed project on OpenBuilds, a forum for open source projects and a parts store with a wide range of components the team used in their project.
Jesse Hellman, Rob Son, Jarod Horn, Geoffrey Hiscox, and Seung Son also put together a video document and celebrating their project. You can see it here: https://youtu.be/3mwkhAkx6W0
