3D Printed Luminous Letters Signage

[Format] Professional e-commerce product main image, square 1:1, high-tech signage-service style on a dark motion-blur ground. [Colors] Near-black background (#0d0d12) streaked with diagonal grey and silver light trails; glowing cyan-blue (#35d6ff) and white as the light accents; red and orange promotional bands. No frame border. [Layout] A small white headline row across the top; the main title on the upper left; a price pill beneath it; a checklist column lower left; a giant 3D letter pair dominating the right half; a red-and-white banner strip across the bottom edge. [Subject] No people. Two enormous 3D extruded letters "3D" rendered as white-faced blocks with glowing cyan-blue stacked side layers, tilted dynamically and flying off the right edge, trailing light streaks. [Headline] Small white caps line "Finely Crafted, Expert Workmanship"; then huge heavy white italic condensed caps "3D Printed Luminous Letters"; below it a row of small white words separated by dots: "Factory / Professional / Custom / One-On-One"; an orange pill "On-Site Service" beside a large white "$99" with "per panel" in small text. [Badges] Lower left, three checkbox rows in white: "Free Design", "3-Year Warranty", "Durable & Sturdy". Bottom banner: a red angled block with bold white text "Free Gift With Order" followed by a white field listing "Power Supply, Timer, Glass Glue". [Mood] Industrial, high-tech and deal-driven; black speed-blur ground with neon cyan glow and urgent red promo bands.
