A charming, stylized 3D character designed in a chibi/cartoon style, perfect for 3D printing as a personalized keychain, school souvenir, or class graduation gift.

Character Design: A young boy with large, expressive eyes and a friendly smile, wearing a sporty pullover hoodie, long pants, and classic sneakers.

Headwear: He is wearing a classic baseball cap facing forward, with detailed hair showing underneath.

Custom Element: The boy is holding a rectangular sign with both hands featuring a prominent, embossed "5B" text (ideal as a souvenir for class 5B).

Keychain Functionality: A solid, vertical eyelet/loop is fully integrated into the top of the cap, making it easy to attach a split ring, chain, or carabiner.

Technical Recommendations for Bambu Studio:
Orientating & Supports: The model stands vertically. Due to overhangs under the cap's brim, the hands holding the sign, and the back of the hoodie, Tree Supports (Slim or Hybrid) are highly recommended. This ensures easy removal and clean surfaces around the face details.

Layer Height: Your current setting of 0.16mm High Quality is an excellent choice for balancing print time and smooth curves on the head and cap. For maximum crispness on the "5B" text or if scaling down, a 0.12mm layer height or a 0.2mm nozzle can also be considered.
