Calibration: First Layer & Multi-Tool Snapmaker U1

This model acts as a comprehensive calibration test designed to validate two critical aspects of your 3D printing setup simultaneously:

1. First Layer Consistency: It provides a clear visual indicator of your bed leveling and Z-offset accuracy across the print surface, ensuring a uniform squish and adhesion.
2. Color/Material Bonding: Specifically optimized for multi-hotend assemblies, IDEX, and Tool Changer systems, this test analyzes the "joint" or seam where different filaments meet. It allows you to inspect the transition for gaps, bleeding, or weak bonding between tool changes.

Use this print to dial in your machine settings for perfect multi-color or multi-material prints.
