Lego Builders
Become a Lego Master Builder - Upload any image to generate a 3D model, automatically converted into a buildable LEGO creation using standard parts. The site displays the final 3D LEGO model alongside step-by-step assembly instructions, turning your photos into real-world physical brick projects.
Built with Astra
We used Astra as the core architectural and automation engine throughout the development lifecycle: Image-to-3D Workflow Architecture: Astra evaluated and identified the necessary tools, APIs, and dependencies required to transform 2D input images into clean, detailed 3D mesh files (.obj). Algorithm & Script Development: Astra architected and wrote the Python scripts that process the .obj file geometry, mapping vertex and volume data to standard, available LEGO piece dimensions and colors. Autonomous Testing & Optimization: Using direct computer manipulation capabilities, Astra automatically loaded the generated LEGO models into BrickLink Studio. It inspected the model's structural integrity, flagged illegal connection points, and tested real-world buildability. Iterative Refinement: Astra fed feedback from its automated Studio reviews back into the script codebase, iteratively refining the Python conversion algorithms until the output consistently produced stable, step-by-step buildable designs.
