Voronoi pattern plasma cut panel. Please do not start cutting the entire sheet if you are a beginner. This panel is designed for thick metal or plywood or any sheet material having sufficient rigidity. If you use plasma cutting, try on a small piece of metal. If you cut this panel out of thin metal it will not have any stiffness. You must additionally make a frame and weld it to the panel for stiffness. Even if cut out of thick metal, alignment may be required.
