Brand new model! 

This is not your average XYZ calibration cube — this enhanced version is designed to test not only dimensional accuracy on all three axes, but also mechanical tolerances and overhang performance.

🔧 Features:

• Built-in Tolerance Pin Test
  Inside the cube, you'll find an integrated cylindrical pin inside a matching hole. This tests your printer’s ability to handle clearance fits (shaft-in-hole tolerance). If your printer is well-tuned, the pin should rotate or move slightly. If it's stuck or too loose, it’s a clear sign of over/under-extrusion or poor calibration.
• Angled Overhang Spike
  On the top, an inclined spike tests your printer’s ability to handle unsupported overhangs. A clean, sharp tip indicates proper cooling and retraction settings.

✅ Great for quick tests and calibration after firmware changes, upgrades, or tuning.
