Create a highly engaging and psychologically effective banner for the homepage of a modern and unique custom furniture website. The design should emphasize 3D printing and personalization, inspired by the Seletti style. Focus on smaller plastic items such as coin holders, decorative vases, and illuminated pyramids, with a marble gray texture. The objects should appear as if they are dynamically emerging out of the computer screen itself, creating a highly realistic and interactive 3D depth effect. Use light blue, white, and black colors to highlight the marble gray material used in 3D printing. Ensure the design conveys a sense of artisanal quality and contemporary style, and includes reflections to enhance realism. Increase the depth of field effect to enhance the 3D look. The image should also be visually aligned with the best and most effective marketing techniques for psychological engagement and customer retention. No text should be included. Size:
