The prompt
Design a professional engineering-grade internal skeleton chassis for a compact environmental monitoring device named PERN V2. The skeleton must be designed as the primary structural frame that holds all internal modules in fixed positions. Overall Device Dimensions Length: 300 mm Width: 220 mm Height: 220 mm Material PETG Wall Thickness 3 mm Assembly All components assembled using M3 screws only. No glue. Support-free FDM printing. --------------------------------------------------- Create dedicated mounting compartments for: ① Air Intake Front left side. 40 mm circular inlet. Replaceable insect mesh. Dust pre-screen. --------------------------------------------------- ② Cyclone Separator Located directly after the air inlet. Diameter 80 mm. Height 120 mm. Four M3 mounting holes. Removable dust cup clearance. --------------------------------------------------- ③ Honeycomb Air Straightener Located immediately after cyclone. Dimensions: 90×90×25 mm. Guide rails. Silicone gasket groove. --------------------------------------------------- ④ Modular Adsorption Cartridge Sliding rail system. Tool-free removal. Dimensions 120×80×35 mm. Centered airflow. --------------------------------------------------- ⑤ Sensor Chamber Located after cartridge. Dedicated mounting plate. Cable routing. Splash protection. Air diffusion space. --------------------------------------------------- ⑥ Fan Module Rear side. 120 mm PWM axial fan. Rubber vibration mounts. Removable grille. 45° exhaust duct. --------------------------------------------------- ⑦ Electronics Chamber Upper compartment. Completely isolated. ESP32 holder. Relay holder. PCB standoffs. Buck converter holder. Fuse holder. Cable channels. USB access. --------------------------------------------------- ⑧ Water Management Module Lower compartment. Completely isolated from electronics. Contains: Humidity Water Tank Cleaning Water Tank Mini Diaphragm Pump Water Sensor Chamber Sedimentation Chamber Drain Outlet Silicone tube holders. --------------------------------------------------- Internal Design Rules No component collision. Minimum clearance: 10 mm. Integrated cable channels. Rounded corners. Structural ribs. Maintenance access. Large removable top cover. Side maintenance door. Transparent windows for both water tanks. --------------------------------------------------- Engineering Goals Compact. Easy maintenance. Professional industrial appearance. Future commercial product. Realistic dimensions. Suitable for CFD simulation. Suitable for STEP and STL generation. Designed for real manufacturing. NOT a concept render. Generate exploded view and assembled view.
