1. Modular Design: The hat body and the circular postal‑letter badge are printed separately and snap together without glue; the adjustable band accommodates a wide range of children’s head sizes. Once printed in PLA or PETG, the piece is ready for 3–8‑year‑olds to wear, suitable for both doll‑like and real‑child applications.

2. Classic Postal Hat Silhouette: The design features a widened, curved brim and double‑layered banding that faithfully replicates the details of an authentic postman’s hat, complete with an original‑style adjustment buckle on the side.

Printing Recommendations

- Recommended Filaments: PLA, PETG;

- Supports: The flat top surface can be printed without supports; only the small badge requires minimal tree‑like supports as needed;

- Placement: Print the hat body with the base facing down to minimize layer lines and achieve a smoother finish.

Application Scenarios

- Doll Accessories: Perfect for decorating standard‑size plush bears and stuffed toys;

- Children’s Outfits: Ideal for holiday costumes, postal‑themed cosplay, or kindergarten activities;

- Desk Decorations: Stand alone as a creative desktop accent, with the badge easily detachable for interchangeable designs.

Structural Highlights

The hat body is molded in one piece, while the badge uses a raised snap‑fit mechanism for flexible assembly and disassembly. The wall thickness is uniform throughout, ensuring the finished part remains stable and lightweight—so even long periods of wear won’t feel burdensome for children.
