Assembly Instructions
Follow the numbered steps in the included illustrated instruction manual. No scissors or glue are required for assembly, as pieces are designed to interlock.
- Preparation: Carefully punch out all puzzle pieces from the foam sheets. Use the provided punch-out tool for smaller or more intricate parts. Organize pieces by number or section as indicated in the manual.
- Base Assembly: Begin by assembling the base structure of the cathedral. Ensure all tabs are securely inserted into their corresponding slots.
- Building Layers: Construct the main body of the cathedral layer by layer, following the numerical sequence in the manual. Pay close attention to the orientation of each piece.
- Dome and Tower Assembly: Assemble the various domes and towers separately before attaching them to the main structure. These often involve folding and interlocking multiple pieces to form the curved shapes.
- LED Light Integration: During specific steps, the manual will instruct you to integrate the LED light wires and bulbs. Ensure the bulbs are placed in the designated openings and wires are routed neatly to the battery box connection point.
- Final Touches: Attach any remaining decorative elements, such as crosses on the domes, to complete the model.

Maintenance
- Cleaning: Gently dust the assembled model with a soft, dry cloth. Avoid using liquid cleaners or abrasive materials, as they may damage the printed surfaces.
- Storage: Store the model in a dry environment away from direct sunlight to prevent fading or warping of the cardboard pieces.
- Handling: Handle the assembled model with care to avoid dislodging pieces.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Pieces do not fit together easily. | Incorrect orientation or slight manufacturing variation. | Ensure the piece is oriented correctly according to the instructions. Gently apply pressure. If a piece is slightly tight, carefully widen the slot with the punch-out tool or a blunt object. Avoid forcing pieces. |
| LED lights are not working. | Batteries are dead, incorrectly installed, or the connection is loose. | Check battery polarity and ensure they are fresh. Verify that the LED light set is securely plugged into the battery box. Ensure the ON/OFF switch is in the 'ON' position. |
| Assembled model feels unstable. | Pieces are not fully interlocked or a section is misaligned. | Review the assembly steps for the affected section. Press firmly on all connections to ensure tabs are fully seated in their slots. |
