1. Product Overview
This manual provides instructions for assembling the nanoblock Black Cat Building Kit, part of the Mini Collection series. This kit allows you to construct a detailed 3D black cat model using micro-sized building blocks. The completed model stands approximately 2.36 inches tall and consists of 110 pieces.

2. Setup and Assembly
The nanoblock Black Cat Building Kit is designed for individuals aged 12 and up, with a skill level rated as 3 out of 5. Due to the extremely small size of the blocks (the smallest being 4x4x5mm), careful attention and dexterity are required during assembly. The kit includes detailed step-by-step instructions to guide you through the building process.
2.1 Unpacking the Kit
Carefully open the packaging and ensure all pieces are present. It is recommended to work on a clean, flat surface to prevent loss of the small blocks.

2.2 Assembly Process
- Refer to the included instruction sheet for a visual, step-by-step guide.
- Identify the different block types and colors.
- Begin assembling the model according to the diagrams. Pay close attention to the placement and orientation of each micro block.
- For very small or intricate connections, using a pair of fine-tipped tweezers may assist in block placement.

2.3 Difficulty Levels
nanoblock kits are categorized by difficulty levels from 1 to 5. This Black Cat model is rated at Level 3, indicating a moderate challenge suitable for experienced builders. The difficulty level is typically indicated on the product packaging.

3. Operating and Display
Once assembled, your nanoblock Black Cat model is ready for display. These models are designed to be collected and showcased as miniature 3D art pieces.
3.1 Displaying Your Model
Place your finished black cat model on a stable surface. Its compact size allows it to fit in small spaces, such as desks, shelves, or display cabinets.

3.2 Handling
While nanoblock models are generally stable, excessive handling or dropping may cause pieces to detach. Handle the model gently, especially when moving it.
4. Maintenance
To keep your nanoblock model in optimal condition, follow these simple maintenance guidelines:
- Cleaning: Use a soft, dry brush or a can of compressed air to remove dust from the model. Avoid using water or chemical cleaners, as these may damage the plastic or affect the block connections.
- Storage: If disassembling or storing the model, keep all blocks in a secure container to prevent loss, as they are very small.
5. Troubleshooting
If you encounter any issues during assembly or with the finished model, consider the following:
- Loose Connections: Some connections, particularly in areas like the legs or tail, might feel slightly loose. If the model is frequently moved and stability is a concern, a small amount of plastic-safe adhesive can be applied to critical joints for a more permanent bond.
- Unclear Instructions: If a step in the instructions appears unclear, re-examine the diagrams carefully. nanoblock instructions are primarily visual; sometimes rotating the diagram or comparing it to previous steps can clarify the assembly.
- Missing Pieces: While rare, if you believe a piece is missing, double-check your work area thoroughly due to the blocks' small size. If a piece is genuinely missing, contact nanoblock customer support for assistance.
