XYZ Calibration Cube 20mm

Precision Calibration Cube — Dial In Your Printer Fast

This calibration cube is a clean, reliable benchmark for tuning X/Y/Z dimensional accuracy, extrusion flow, and surface quality on any FDM printer. Designed with crisp embossed axis letters and sharp edges, it gives you instant visual feedback on how well your machine is performing.

What This Model Helps You Test

• X/Y/Z accuracy — Check if your printer is overshooting or undershooting dimensions. This should be exactly 20mm cubed.
• Extrusion tuning — Spot over‑extrusion, under‑extrusion, or inconsistent walls.
• Layer alignment — Identify ringing, ghosting, or mechanical backlash.
• Z‑axis consistency — Evaluate layer height precision and vertical smoothness.
• Flow calibration — Perfect for dialing in filament profiles on Bambu, Prusa, Creality, and more.

Print Details

• No supports required
• Fast print — Ideal for quick tuning sessions
• Optimized geometry for clean edges and readable letters
• Works with any filament (PLA recommended for baseline testing)

Why Makers Love It

This cube is simple, fast, and incredibly informative. Whether you're setting up a new printer, tuning a new filament, or diagnosing mechanical issues, this model gives you clear, repeatable results you can trust.
