Ironing test for 0.4mm nozzle

Ironing test model designed to help find the best surface smoothing settings for Bambu Lab 3D printers. The model features a grid of small square test areas, each printed with slightly different ironing parameters, allowing for easy visual comparison of surface quality.

Each row and column represents a change in settings such as ironing flow, speed, or spacing, making it possible to identify which combination produces the smoothest and most consistent top surface. The labeled percentages and values around the grid help track and reproduce the optimal configuration.

The design is simple and practical, making it easy to print quickly and evaluate results at a glance. It is a useful calibration tool for improving print quality, especially when aiming for clean, flat, and visually appealing top layers.
