Build Tips
A five-minute sort by color or piece type before starting saves time hunting for specific bricks mid-step.
Follow the numbered steps in sequence — structural elements early in the build support everything that comes after.
Once built, direct sunlight yellows ABS plastic over time. A display case or UV-filtered shelf glass keeps colors vibrant.
