The prompt
You are a mechanical CAD engineer. Using Python + CadQuery, model my final-year project: “Design and Fabrication of an Indirect Solar Dryer with a Temperature Control System” for tomato drying in Zaria, Nigeria. Units: mm. Model it as built. GIVEN — DO NOT CHANGE: - Collector interior: 474 W × 950 L, tilted 11° upward toward chamber. - Collector: plywood trough, matte-black metal absorber, glass cover. - Drying chamber internal: 500 W × 500 L × 600 H, plywood. - Two 500 × 500 mm wire-mesh trays, 200 mm spacing; bottom/top clearance 100 mm. - Side hinged plywood access door. - Roof vent: conical metal cap with 50 mm hole and 50 mm diameter 12 V DC fan. - 4 DS18B20 sensors: collector inlet/outlet, absorber, chamber inlet. - Electronics: Arduino Nano, relay, SD module, battery pack. ASSUMPTIONS — SHOW ON DRAWINGS: - Plywood: 12 mm. - Collector outer: 498 × 974 mm; trough depth 100 mm. - Insulation: 25 mm; absorber: 1 mm, 470 × 946 mm. - Glass: 4 mm; 50 mm air gap; glazing frame 25 × 12 mm. - Legs: 40 × 40 mm; collector low edge 300 mm above ground; chamber positioned so outlet aligns with inlet; 2 cross braces. - Chamber inlet: 400 × 100 mm at bottom of front wall. - Tray rails: 20 × 20 mm; tray frame 490 × 490 mm; mesh 1 mm simplified as thin plate. - Vent: 150 mm base × 100 mm high cone; fan body 50 × 50 × 15 mm with 4 mounting holes. - Door: 350 × 450 mm, 2 hinges and latch. - Electronics box: 200 × 120 × 70 mm on rear wall; model Nano (45 × 18 mm), relay, SD module and battery as simple blocks. - Sensors: cylinders Ø6 × 25 mm with clips; positions as specified in the original design. PARTS: SD-01 Legs/braces SD-02 Collector trough/insulation SD-03 Absorber SD-04 Glazing frame SD-05 Glass SD-06 Drying chamber SD-07 Door/hinges/latch SD-08 Tray (used twice) SD-09 Vent cap SD-10 Fan SD-11 Electronics enclosure SD-12 Four sensors SD-00 Complete assembly DELIVER: 1. STEP file for every part + complete assembly, correctly positioned. 2. PNG renders: assembly isometric, exploded airflow-path view with numbered parts, and individual part views. 3. 2D drawings in PNG + PDF: assembly front/side/top, A-A airflow section, and dimensioned drawing for every part. Use first-angle projection and title blocks containing project title, part, scale, units, material, “Drawn by Abdulwahab Ridwan Opeyemi”, and date. Show all assumptions on each sheet. 4. BOM: part number, name, material, quantity. 5. One Python script with a parameter block at the top so changing dimensions regenerates everything. RULES: - Use buildable geometry and preserve all GIVEN dimensions. - Run collision/overlap checks and report results. - Re-import/check every STEP and report each bounding box. - If anything is unclear, make a sensible assumption and list it separately. - Generate all files automatically from the Python script.
