Rectangular wooden frame cover with divider and slots

Create directly a single clean parametric CAD solid according to the following dimensions. Do not ask questions and do not add components or features not explicitly specified. Overall external dimensions: X = 500 mm Y = 430 mm Z = 104 mm Create a rectangular perimeter wooden frame with: wall thickness = 22 mm internal opening = 456 mm × 386 mm The perimeter walls must extend continuously from Z=0 to Z=104. Create two internal cavities separated by one continuous horizontal solid divider: lower cavity: Z = 0 to 34 mm horizontal divider: thickness = 10 mm Z = 34 to 44 mm upper cavity: Z = 44 to 104 mm The lower cavity must remain open from the bottom. The upper cavity must remain open from the top. Do not add an external bottom panel or top cover. Create one circular through-hole in the horizontal divider only: diameter = 42 mm center X = 250 mm center Y = 215 mm The hole must be exactly centered in the 500 × 430 mm footprint. Create four horizontal rectangular through-slots in the two opposite vertical walls parallel to the X axis. There must be two slots on the wall at Y = 0–22 mm and two corresponding aligned slots on the opposite wall at Y = 408–430 mm. All four slots: width along X = 103 mm height along Z = 3.8 mm center X = 250 mm pass completely through the 22 mm wall thickness Lower slot: Z = 8.1 to 11.9 mm centerline Z = 10 mm Upper slot: Z = 24.1 to 27.9 mm centerline Z = 26 mm Vertical centerline distance between the two slots = exactly 16 mm. The slots on the two opposite walls must be perfectly aligned with each other and centered horizontally. They must not be moved toward the corners. Apply external corner radius: R = 3 mm Keep all primary dimensions parametric: OverallLength = 500 OverallWidth = 430 OverallHeight = 104 WallThickness = 22 DividerThickness = 10 DividerBottomZ = 34 HoleDiameter = 42 SlotWidth = 103 SlotHeight = 3.8 LowerSlotCenterZ = 10 UpperSlotCenterZ = 26 CornerRadius = 3 Maintain symmetry about X = 250 mm and Y = 215 mm. Do not create: rollers, belt, tank, scrapers, motor, supports, fasteners, additional holes, additional slots, upper lid, bottom panel, decorative features, assemblies, or external components. Generate only the parametric CAD geometry described above as one manufacturable wooden cover body suitable for STEP export.

Every value above is a live dimension. Open a model like this in the editor and each one becomes a slider you can drag before exporting.
