This “Boo!” sign is a seasonal decorative plaque featuring a script style “Boo!” with a small bat perched above the letters. The model was created from an SVG silhouette and optimized for FDM 3D printing as a single part.

Use cases:

Quick Halloween decorations for doors, windows or shelves

Photo prop for parties or seasonal displays

Design notes:

The design is a closed silhouette — no supports required when printed flat on the bed.

Edges are slightly rounded to avoid sharp corners when printed.

Scale up or down freely, but keep at least 150 mm width for best legibility.
