The prompt
Create a miniature passive acoustic horn for the built-in speaker of an M5Stack M5StickS3 (48×24×15 mm). The speaker has 3 sound outlet holes. Make a single tiny attachment that covers only these 3 holes and redirects their sound forward. No electronics, no case, no grille. Use a very short curved horn / acoustic reflector with smooth internal walls and gradual expansion. Maximum size: 25×15×4 mm. Wall: 0.8–1 mm. Minimum channel: 3 mm. Thin silicone-adhesive mounting flange. Optimize for maximum perceived loudness and forward projection, not appearance. FDM-printable PLA/PETG, preferably support-free. Export STL and STEP.
