First Layer Z height calibration

cults3d

My Custom Design for Z-Height Calibration It's large enough to inspect first-layer smoothness yet compact enough to save time. The central square must be perfectly flat and even. A circular hole at the corner should be well-defined and clear. The outer square edge should adhere flawlessly to the bed, with a noticeable gap between it and the central square. The outermost circle should bond smoothly and be rounded, just touching the corner of the square. One single line pattern and three additional patterns are included. You can easily add more and customize them in your slicer to fit your specific needs.
