What you getA high‑contrast lithophane panel derived from the included devil‑girl artwork, tuned for strong depth separation so facial features, horns, and the glowing “HALLOWEEN” sign pop when backlit. The STL is sized for common build plates and prints flat or upright depending on your lighting setup.

Key featuresOptimized grayscale height mapping with embossed sign letters to read clearly under LED light, producing a poster‑like finish.

Two orientations provided: vertical panel for frames and flat plaque for window/backlight stands; border frame prevents edge light bleed.

Works with warm‑white LEDs to mimic candle glow; excellent detail even at 0.2 mm layers on standard FDM printers.

Technical specsFormat: STL; versions: Framed vertical, Flat plaque; thickness gradient ~1.2–3.0 mm; recommended size ~180×240 mm.

Print settings: 0.12–0.2 mm layer height, 100% infill (concentric), 3 walls; print in white or natural PLA; no supports.

Lighting: LED strip or panel behind; avoid heat sources or open flame.

Usage notesMount in a simple photo frame with LED panel, or use a printed stand; ensure light is diffused evenly for best contrast. Show both day and backlit photos in the listing and include a short note that the digital artwork is included solely for lithophane conversion.
