This is a comprehensive bed leveling test model designed to check the Z-axis height consistency across the entire build plate. It features a 3x3 grid of test points, evenly distributed to cover the full print area.

Use this model to:

• Verify and fine-tune your printer’s bed leveling and Z-offset settings.
• Detect high or low spots on the build plate that could affect print adhesion and quality.
• Ensure consistent first layer height across all areas of the bed.

Print this model with your usual first layer settings and observe the extrusion at each point — the filament should adhere evenly without gaps or squishing. Adjust your printer’s bed leveling accordingly based on the results.
