Authentic mid‑century diner blade sign modeled for HO scale (1:87) dioramas. This printable mini reproduces the boxed sheet‑metal look and star motif of 1950s roadside signage and includes an integrated mounting tab for easy attachment to storefront facades or canopy mounts. Designed for fine detail: thin‑walled lettering and subtle reliefs preserve the retro character at small scale. Ideal for model railroad layouts, architectural models, and diorama scenes that need a period‑correct storefront accent. Printing notes: best printed vertically with supports on the mounting tab. Recommended layer height 0.08–0.20 mm for filament or high‑resolution resin printing. Use a brim/raft for thin parts and post‑process with light priming before painting. Glue the mounting tab to your building surface and touch up seams with filler if needed. Includes: one blade sign model sized for HO scale. No physical item shipped — digital 3D file for printing.
