Curved Under‑Desk Treadmill – Side Frame & Tread Slats Assembly

"Create a 3D CAD model of a two-piece side frame and tread slat assembly for a compact manual curved under-desk treadmill. Side Frame Component: - Overall dimensions: 1100 mm long x 160 mm tall x 18 mm thick. - Material/Appearance: 18 mm Baltic Birch Plywood. - Top Edge Profile: A continuous curved deck arc defined by a 1000 mm radius curve with a 40 mm center dip relative to the ends. - Mounting Features: A series of 84 through-holes (8.2 mm diameter) spaced at 25 mm intervals along the curved top contour, located 15 mm below the top edge to accept M8 bearing axle bolts. - Structural Tie Rod Holes: 4 through-holes (10.2 mm diameter for M10 rods) positioned strategically near the bottom edge and corners (25 mm from bottom, spaced evenly at 300 mm intervals). - Base Profile: Flat bottom surface (600 mm ground contact width) with smooth 50 mm fillet transitions leading up to the front and rear guide roller mounts. Tread Slat Component: - Dimensions: 400 mm length x 30 mm width x 12 mm thickness. - Material: Hardwood slat. - Features: Top surface features 2 mm chamfers on long edges. Bottom surface includes two recessed countersunk mounting holes (4.5 mm diameter, 8 mm head clearance) spaced 350 mm apart to secure to flexible drive belts. Assembly Layout: - Render one side frame plate and a linear array of 5 sample tread slats positioned parallel to each other across the 1000 mm radius curved deck top edge with a 2 mm gap between slats. All dimensions in mm."
