The prompt
Design a compact, two-part 3D-printable parametric electronics enclosure shell with snap-fit or M3 screw-boss standoffs, customized for an AgTech machine condition monitoring system. Components to enclose inside: 1. ESP32 DevKit V1 (30-pin board, approx. 28mm x 55mm x 12mm): Mount horizontally at the base with clearance for a micro-USB / USB-C port cutout on the side wall. 2. MPU-6050 Accelerometer/Gyroscope breakout board (approx. 20mm x 16mm x 4mm): Mount rigidly flat near the bottom plate on dedicated M2 standoffs for accurate vibration transfer from the machine. 3. SH1106 1.3-inch OLED Display Module (approx. 35.5mm x 33.5mm x 4mm): Mount on the top face cover with a centered 30mm x 17mm rectangular viewing cutout window. Design Specifications & Constraints: - Overall Style: Compact, industrial, Wall-E / AgTech aesthetic with rounded outer vertical edges (R = 4mm). - Tolerances & Clearance: Include a uniform 1.5mm to 2.0mm internal wiggle room / safety tolerance around all internal component footprints for easy assembly, wire management, and thermal dissipation. - Wall Thickness: 2.5mm uniform shell wall thickness optimized for FDM 3D printing in PLA/PETG. - Cable Routing & Ports: Include internal wire-management channels between the ESP32 and upper OLED display, plus side ventilation slots for passive cooling. - Assembly: Split enclosure into a main base chassis and a removable top lid secured by four corner M3 threaded brass insert standoffs (D = 4.2mm holes).
