Please read these instructions carefully before beginning assembly to ensure a successful and enjoyable building experience.
2. Safety Information
WARNING: CHOKING HAZARD - Small Parts. Not for children under 3 years.
The Nanoblock NBH_117 set contains many small pieces. Keep all blocks and packaging materials out of reach of young children and pets to prevent accidental ingestion. This product is recommended for ages 12 and up due to the intricate nature and small size of the components.
All Nanoblock components are made from non-toxic plastic materials.

- Approximately 240 micro-sized building blocks in various shapes and colors (primarily grey and green).
- One detailed instruction sheet with step-by-step assembly diagrams.
- One base plate for the model.
If any parts are missing or damaged, please refer to the 'Warranty and Support' section for assistance.
4. Setup
- Prepare Your Workspace: Choose a clean, well-lit, and flat surface for assembly. A clear workspace will help prevent loss of small pieces.
- Organize Blocks: Carefully open the block bags. It is often helpful to sort blocks by color and size before beginning assembly. This can significantly speed up the building process.
- Review Instructions: Familiarize yourself with the instruction sheet. Pay attention to the symbols and the sequence of steps.
5. Assembly Instructions
The Nanoblock NBH_117 Stonehenge model is assembled by following the detailed, step-by-step diagrams provided in the included instruction sheet. The assembly process typically involves building the model layer by layer from the base upwards.
- Start with the Base: Begin by placing the initial layer of blocks onto the base plate as indicated in the instructions.
- Follow Diagrams Precisely: Each step in the instruction sheet shows which blocks to use and where to place them. Ensure blocks are firmly connected.
- Layer by Layer: Continue adding layers of blocks, carefully checking the orientation and placement for each piece.
- Patience is Key: Due to the small size of Nanoblocks, precision and patience are important. If a block is difficult to place, ensure it is correctly aligned.

6. Maintenance and Care
To ensure the longevity and appearance of your Nanoblock model:
- Cleaning: Dust can be removed with a soft brush or a can of compressed air. For deeper cleaning, gently wipe with a slightly damp cloth. Avoid harsh chemicals or abrasive cleaners.
- Storage: Store the assembled model or loose blocks in a cool, dry place away from direct sunlight to prevent discoloration or material degradation.
- Handling: Handle the model with care, especially when moving it, to prevent pieces from detaching.
7. Troubleshooting
- Missing Pieces: Double-check your workspace and packaging. If a piece is genuinely missing, refer to the 'Warranty and Support' section.
- Difficulty Connecting Blocks: Ensure blocks are correctly oriented and aligned. Apply gentle, even pressure. Avoid forcing blocks, as this can damage them.
