7. Troubleshooting

7.1 Difficulty Connecting Pieces:

• Ensure you are using the correct pieces as indicated in the instructions. Small differences in size or shape can prevent proper connection.
• Apply firm, even pressure when connecting bricks. Avoid forcing pieces, as this can cause damage.
• If a piece seems too tight or won't fit, try wiggling it gently or checking for any obstructions or misaligned studs.

7.2 Model Instability:

• Double-check previous steps to ensure all connections are secure and no pieces are misplaced or loosely attached.
• Ensure the base plates are flat and on a stable surface during assembly to prevent warping or uneven construction.
• Verify that all interlocking connections are fully engaged.
