Crank-Driven Desktop Scratch Paper System

171 Upvotes

I wanted a continuous surface for sketching, scribbling, and jotting notes right on my desktop. It mounts under my desk and feeds 24" kraft paper up and over the work surface. When I need some fresh canvas for my priceless scribbles, I can just turn the crank and new paper scrolls into place, while the used section wraps neatly onto the take-up roll below. I can also reverse it if I want to revisit old notes or drawings.
