The prompt
Design a **compact, slim and low-profile 3D-printable enclosure** for: - ESP32 DevKit V1 / ESP32-WROOM-32 - 0.96" OLED SSD1306 - Micro SD card module - KY-040 rotary encoder with push button - MAX31865 RTD/PT100 module The enclosure should consist of a **lower housing and removable top cover**. ### Main priority Make the enclosure **as flat and compact as possible**. Keep the overall height very low. Arrange the ESP32, Micro SD module and MAX31865 **side-by-side rather than stacking them**. If necessary, make the enclosure slightly wider or longer instead of making it higher. ### Top cover The **OLED and KY-040 encoder must be integrated into the top cover**. - OLED recessed into the top cover and clearly visible. - KY-040 mounted next to/below the OLED. - Encoder shaft accessible from the outside and push button fully usable. - Keep the top cover thin but strong. ### Connections - ESP32 USB port accessible from the side. - Micro SD card accessible from the outside. - PT100 cable connection accessible from the outside. ### Construction - 2–2.2 mm wall thickness - 2–3 mm clearance around PCBs - Low-profile PCB mounting posts - M2.5/M3 screws - 4 screws for the top cover - Rounded corners and clean professional design - Minimal supports for FDM printing - Suitable for PLA/PETG - Allow 0.2–0.4 mm tolerance for 3D printing. Keep the internal wiring short and organized. The top cover must close without touching the electronics or cables. Use the **actual dimensions of the modules if available**. Make the CAD model parametric so dimensions can be adjusted later. Export as **STL, 3MF and STEP**.
