## 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.

## About SpeakCAD

SpeakCAD is the most intuitive CAD for 3D printing, made for people who own a 3D printer and need a part that fits something they have: tap a face and type a size to shape it with simple tools, or describe it to the AI, on your phone or computer, and download a print-ready STL, 3MF or G-code sliced for your printer.

SpeakCAD works inside ChatGPT and Claude as a plugin (an MCP server): ask the assistant for a part with its measurements and SpeakCAD's own CAD AI designs it, shows it in 3D in the chat and hands over a print-ready STL, 3MF or G-code sliced for your printer.
