This is a fully 3D-printed “perpetual scratch paper system” It's mounted to the underside of my desk and provides a continuous surface for scribbling and sketching. Whenever I need a clean spot to write, I just reach down and turn the crank. New paper unspools and slides up across the desktop, while the used paper feeds down and wraps neatly onto the take-up roll below. (paper can be run forwards and backwards)
