4. Setup and Assembly Instructions
The nanoblock Gudetama kit has a difficulty level of 2 out of 5. Patience and attention to detail are key for a successful build.
- Preparation: Clear a well-lit, flat, and stable workspace. Organize your nanoblock pieces by color and shape if desired, though the small number of pieces for this model may not require extensive sorting.
- Review Instructions: Carefully examine the included instruction booklet. It will provide step-by-step diagrams for assembling your Gudetama model.
- Start Building: Begin by following the diagrams from the base upwards. Pay close attention to the orientation and placement of each block.
- Piece Placement: Use gentle pressure to connect the blocks. If a piece does not fit easily, double-check the instructions to ensure correct placement. Avoid forcing pieces, as this can damage them.
- Layer by Layer: Nanoblock models are typically built layer by layer. Ensure each layer is securely connected before proceeding to the next.
- Detailing: The final steps will involve adding smaller detail pieces to complete Gudetama's features.

5. Operating and Display
Once assembled, your nanoblock Gudetama model is ready for display. It is a static model designed for decorative purposes.
- Place the model on a flat, stable surface to prevent accidental falls.
- Avoid placing it in direct sunlight or near heat sources, which could potentially warp the plastic over time.
- The model is stackable, allowing for creative display options with other nanoblock creations.
6. Maintenance
To keep your nanoblock Gudetama model in optimal condition:
- Cleaning: Use a soft, dry brush or a can of compressed air to remove dust. For stubborn dirt, a slightly damp cloth can be used, but avoid excessive moisture.
- Handling: Handle the model gently. While nanoblocks are designed to connect securely, excessive force or dropping can cause pieces to detach.
- Storage: If disassembling for storage, keep all pieces in a sealed container to prevent loss.
7. Troubleshooting
- Missing Pieces:
- Carefully re-check your workspace and packaging. Due to the small size of nanoblock pieces, they can be easily overlooked. If pieces are genuinely missing, contact customer support (see Section 9).
- Difficulty Connecting Pieces:
- Ensure the pieces are correctly oriented according to the instructions. Apply firm but gentle pressure. If a piece still doesn't fit, verify it's the correct piece for that step.
- Model Instability:
- Review previous steps to ensure all connections are secure and pieces are correctly aligned. A loose connection in an earlier layer can affect the stability of subsequent layers.
