Plastic board and cutting mat: Insert or secure a cutting mat onto a plastic board to create a stable surface for cutting tasks. Ruler with holes for the knife: Secure a ruler with thin holes, allowing the knife to penetrate, on the plastic board (or use a tool that acts as a slider). Left and right movement: Use a fixture that allows the ruler to move left and right, enabling it to be positioned as desired during work. Up and down movement using springs: Attach springs to allow the ruler to move up and down, enabling it to be lifted or lowered as needed. This setup should facilitate easy movement of the ruler and perform cutting tasks easily.
