Plastic board and cutting mat: Secure the cutting mat on top of the plastic board to create a stable surface for cutting tasks. Ruler with holes for a knife: Fix a ruler with thin holes that allow a knife to pass through (or a tool that acts as a slider) on the plastic board. Left and right movement: Use a fastening device 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 a spring to allow the ruler to move up and down, so it can be raised or lowered when needed. This facilitates easy movement of the ruler and the cutting tasks. Use a cutter knife for cutting.
