Enclosure Lid - Solar Recess & 18650 Battery Cradle

Generate a 3D CAD model of a rectangular electronic enclosure lid requiring high mechanical precision on both the top and bottom faces. 1. Base Plate: Create a solid rectangular plate with outer dimensions of 94.0 mm (X-axis) by 69.0 mm (Y-axis) and a uniform thickness of 2.0 mm (Z-axis). 2. Corner Mounting Holes: Cut four 3.2 mm circular through-holes in the four extreme corners of the plate. Add countersinks to the top surface of all four holes to allow M3 machine screws to sit flush. 3. Underside Weather Seal: On the bottom surface of the lid, extrude a continuous raised ridge (1.5 mm wide and 1.5 mm tall) running completely around the perimeter. Inset this ridge slightly from the outer edge so it fits inside a 90x65mm box. 4. Underside Battery Cradle (Rails & Center Boss): On the bottom surface, positioned squarely in the lower half of the lid along the Y-axis, extrude two parallel rectangular guide rails. Each rail must be 75.0 mm long (running along the X-axis), 2.0 mm wide, and 5.0 mm tall. Space these two rails exactly 21.5 mm apart to tightly cradle the sides of an 18650 battery holder. Exactly centered between these two rails, extrude a single circular screw boss (5.0 mm outer diameter, 2.0 mm inner pilot hole, 3.0 mm height) to lock the holder down. 5. Topside Solar Recess: On the top surface of the lid, positioned in the upper half of the Y-axis, cut a shallow rectangular recess measuring 50.0 mm by 30.0 mm. Cut this recess to a depth of exactly 1.2 mm so a solar panel can be seated flush. 6. Wire Pass-Through: Cut a 3.0 mm circular hole directly through the center of the topside solar recess area, passing entirely through the 2.0 mm thickness of the lid to the underside.
