This is a compact, technical calibration and printability test specifically optimized for fine-detail printing, such as with a 0.2mm nozzle setup.

I designed this object to stress-test your printer's precision, cooling, and extrusion capabilities in one quick print.

Key Test Features:

• Bridging Cavities: Test how well your printer handles spans without support.
• Overhang & Slope Profiles: Check for sagging and layer adhesion angles.
• Overflow & Tolerance Zones: Fine-tune your extrusion multiplier to prevent over-extrusion.
• Deformation & Cooling Check: The structure challenges your part-cooling fan to prevent warping on thin walls and sharp geometry.
