I built this fully 3D-printed “perpetual scratch paper system” to give myself a continuous surface for sketching, scribbling, and jotting notes right on my desktop.

It mounts under the desk and feeds 24" kraft paper up and over the work surface. When I need a fresh canvas, I just turn the crank—new paper scrolls into place, and the used section wraps neatly onto the take-up roll below. You can also reverse it if you want to revisit old notes or drawings.

Details:

• Under-desk mounted with recessed screws
• Dovetail joints make the frame easy to remove and change out paper
• Crank-operated take-up roll winds used paper below the desk
• Bi-directional scroll lets you move the paper forwards and backwards
• Designed for 24” kraft paper rolls on 1” diameter tubes
