Ornate Gothic quatrefoil tracery decorative panel designed for 3D printing. Ideal for adding stone-style window and facade detail to HO scale model buildings, dioramas, and model railroad layouts. The high-detail tracery works as a window insert, screen panel, or facade ornament — perfect for restorations, kitbashing, and scratch-built structures. Files: STL format for straightforward printing. Print orientation flat for best detail; light supports may be required depending on your printer. Recommended print settings: 0.1–0.2 mm layer height, 15–25% infill. Finish with light sanding and painting to match miniature stonework.
