Build Tips

1

A five-minute sort by color or piece type before starting saves time hunting for specific bricks mid-step.

2

Follow the numbered steps in sequence — structural elements early in the build support everything that comes after.

3

Keep the instruction booklet after building — it's the most reliable reference for disassembly, cleaning, or reassembly after storage.
