The prompt
Create a parametric wooden inner cover (crown board) for a standard 10-frame European Dadant-Blatt beehive. Model ONLY the wooden inner cover; do not model belt, rollers, scrapers, reservoir, motor or electronics. MAIN DIMENSIONS - Outer size: 500 × 430 mm - Rectangular wooden perimeter frame + flat central wooden panel - Realistic commercial wooden construction, suitable for CNC/woodworking - Straight walls, no decorative features, no unnecessary ventilation or feeder holes - Keep Cover_Height, wall thickness and panel thickness editable parameters. BELT SLOTS Create exactly 4 horizontal rectangular THROUGH-SLOTS in the VERTICAL SIDE WALLS, never on the top surface: - 2 slots on one side - 2 perfectly corresponding slots on the opposite side - opposite slots aligned to create 2 straight parallel belt paths across the hive - slots positioned in the central functional area, NOT near corners - symmetric geometry Belt reference: - width: 70 mm - thickness: 5–7 mm (nominal 6 mm) - clearance: 1 mm per side Size slots accordingly for free belt movement. Use small edge fillets where useful to prevent belt damage. VERTICAL POSITION Slots must allow the belt to travel horizontally very close to the frame top bars when installed. Do not place slots arbitrarily at mid-wall height. Maintain the functional bee-space constraint: target clearance between belt and adjacent inner-cover/divider surface <9 mm. PARAMETERS Length=500 mm Width=430 mm BeltWidth=70 mm BeltThickness=6 mm SlotClearance=1 mm Keep editable: CoverHeight WallThickness PanelThickness SlotWidth SlotHeight SlotZPosition Slot1Position Slot2Position CornerRadius CONSTRAINTS Opposite walls parallel; adjacent walls perpendicular; all slots horizontal; opposite slots perfectly aligned; slot pairs symmetric; no slot intersects a corner; maintain enough wood around slots for structural strength. Generate a clean parametric solid representing ONLY the wooden inner cover, suitable for later STEP export.
