Introduction
Welcome to the world of nanoblock! This instruction manual provides essential information for assembling, maintaining, and understanding your nanoblock Black Cat Building Kit (Model NBC-281). This kit allows you to create a detailed 3D model of a black cat using micro-sized building blocks. Please read this manual thoroughly before beginning assembly.
Safety Information
WARNING: CHOKING HAZARD - Small Parts.
- This product contains very small parts and is not suitable for children under 3 years of age.
- Recommended age for assembly is 13 years and up. The manufacturer specifically recommends ages 15+ for this model due to its complexity.
- Keep all blocks and packaging materials away from infants and young children to prevent accidental ingestion.
- Exercise caution during assembly to avoid eye strain or discomfort from handling small pieces.
Package Contents
Your nanoblock Black Cat Building Kit package should contain the following items:
- Approximately 110 micro-sized building blocks required to construct the Black Cat model.
- Detailed step-by-step instruction sheet.

Setup and Assembly
Follow these steps to assemble your nanoblock Black Cat model:
- Preparation: Unpack all contents and lay out the blocks on a clean, well-lit surface. Due to the micro size of the blocks (smallest part is 4x4x5mm), consider using tweezers for easier handling, especially if you have larger fingers.
- Follow Instructions: Refer to the detailed step-by-step instruction sheet included in your kit. Each step will guide you through the placement of specific blocks.
- Difficulty Level: This model is rated at a Level 3 difficulty (on a scale of 1 to 5, with 5 being most advanced). Take your time and pay close attention to the diagrams.
- Precision: Ensure each block is firmly connected to the previous one to create a stable structure.

Operating and Display
Once assembled, your nanoblock Black Cat model is designed for display. Place it on a stable, flat surface where it can be admired. While the connections are generally secure, avoid excessive handling or dropping the model to prevent blocks from detaching.
Maintenance
To keep your nanoblock model in optimal condition:
- Cleaning: Gently dust the model with a soft brush or a can of compressed air. For more stubborn dirt, a slightly damp cloth can be used, but avoid excessive moisture.
- Storage: If disassembling or storing, keep all blocks in a secure container to prevent loss of the small pieces.
- Environment: Avoid prolonged exposure to direct sunlight or extreme temperatures, which could potentially affect the plastic blocks.
Troubleshooting
| Issue | Possible Solution |
|---|---|
| Missing Pieces: | Carefully check the packaging and surrounding area. If pieces are genuinely missing, contact nanoblock customer support for assistance. |
| Difficulty Assembling: | Re-examine the instruction diagrams closely. Ensure blocks are oriented correctly. Consider using tweezers for better grip and precision with the small blocks. |
| Model Instability: | Ensure all blocks are pressed firmly together. If certain joints (e.g., between legs and body) feel loose, a small amount of plastic-safe adhesive can be used for permanent stability, though this is generally not required for nanoblock models. |
