About this model

Enclosure for an ESP32 microcontroller with an LCD display and relay module. The box measures 220 × 145 × 42 mm and holds a 16×2 LCD (80 × 36 mm board) mounted on the lid with M2.5 screws, an ESP32 on M3 standoffs below it, and a relay module in a separate lower chamber. A divider keeps the relay area isolated; five cable holes and a DHT11 sensor slot on the front allow external connections. Print the box open-side up without supports, then the lid face-down beside it.
