Here is a clean, catchy MakerWorld description for your calibration cube, focusing on diagnosing print issues like z-banding and layer consistency!

🟥 Ultimate 3D Printer Diagnostic Cube (Z-Banding & Layer Tester)

Are you trying to track down nasty layer lines, inconsistent extrusion, or Z-axis artifacting? This straightforward diagnostic model is designed to help you analyze, tweak, and perfect your printer's layer consistency!

Unlike complex calibration models that waste a ton of filament, this cube gives you large, flat vertical faces specifically optimized to catch shadows, making it incredibly easy to visually identify mechanical issues like Z-banding, loose belts, or unstable hotend temperatures.

🔍 What to Look For After Printing:

• Horizontal Lines (Z-Banding): Look at the faces under angled lighting. If you see repeating ridges at specific heights, check your Z-axis lead screws for dirt, bends, or binding.
• Wavy Corners (Ringing/Ghosting): If you notice "echoes" of the corner stretching across the face, your printing speed might be too high or your belts need tightening.
• Rough Tops: Perfect for dialing in your top-layer flow rate and ensuring a smooth finish without gaps or over-extrusion scars.

🖨️ Recommended Print Settings

For a true diagnostic benchmark, you want to eliminate slicer tricks and see how your hardware actually performs:

• Material: PLA or PETG in a solid, non-silk color (grey, white, or red work best for catching layer shadows).
• Layer Height: Use your standard profile height (0.20mm or 0.16mm).
• Infill: 10% to 15% (Grid or Gyroid).
• Wall Loops: 2 or 3 loops.
• Supports: None needed.
• Cooling: Keep your part cooling fan at its standard settings to check for consistent layer-to-layer bond appearance.

If this model helps you track down a hardware issue or dial in your slicer settings, please leave a review and upload a photo of your print! Happy tuning!
