Pikachu keychain

Small keychain Pikachu with an adorable, compact, and easy-to-print design. It has a clean silhouette, marked details on the eyes, cheeks, and tail, and a format designed for fast, good-quality, and uncomplicated printing. Ideal as a gift, backpack accessory, or detail for Pokémon fans, with multicolor option via AMS and simple supports if the model needs them.”
To fit better in under 3 hours, I would make it flat, in a single piece, with a soft relief and an integrated ring. A very comfortable size would be 45 to 55 mm high and about 4 to 5 mm thick.
Parameters
•    Material: PLA Basic or PLA Matte.
•    nozzle: 0.4 mm; PLA is compatible with AMS/AMS lite and Bambu lists it as a valid material in that system.
•    nozzle temperature: use the default PLA profile; the Bambu guide places PLA at 190-240 °C.
•    Bed: smooth or textured PEI plate; for PLA, Bambu recommends 45-65 °C.
•    Layer height: 0.16 mm to balance time and detail; if you want a cleaner surface, 0.12 mm also works well as a fine adjustment, and Bambu users report good results with the nearly default PLA profile.
•    Walls: 3 perimeters.
•    Top/bottom layers: 4-5.
•    Infill: 10-12% gyroid; the gyroid pattern is an option that Bambu users employ with PLA for good quality prints.[reddit]
•    Seam: rear or “nearest” hidden on the least visible side.
•    Line width: standard.
•    Speed: standard/silent profile if you prioritize finish.
