In this video, I’ll walk you through the full design and assembly process, explain key components like the ER11 chuck, 775 motor, belt drive, and linear bearings—and share what worked, what didn’t, and how much it all cost.
Was it overkill? Maybe. Was it worth it? You’ll find out.
Whether you're into 3D printing, DIY tools, or just want cleaner drill holes—this video might inspire your next project.
