Fully parametric, highly precise ego-compatible brick generator. Optimized for FDM 3D printing with solid bottom tubes and reinforcement chamfers to prevent layer splitting.

Description: Create any size of building brick instantly! This OpenSCAD script is highly tuned for FDM 3D printing. It doesn't just stretch a 3D model; it mathematically calculates the exact number of studs and perfectly places internal structures based on the standard 8mm pitch.

Key Features:

• Dimension Inputs: Just type your desired length/width in mm (it automatically snaps to 8mm increments).
• FDM Optimized: Internal bottom tubes are solid by default and feature a reinforcement chamfer at the ceiling to prevent snapping along layer lines.
• Custom Tolerances: Adjust the outer clearance (default 0.1mm) and stud diameter (default 5.0mm) for the perfect press-fit on your specific printer.
• Tile Mode: Turn off top studs to generate smooth finishing tiles.
