minimalist cube lamp 3d model

Create a clean, symmetrical, watertight 3D model of a minimalist table lamp. Body: exact cube, 200×200×200 mm, flat faces, sharp 90° edges. Globe: true sphere, Ø150 mm, centered on top; embed it 28.7 mm into the cube so 121.3 mm remains visible. Front face only: four identical cylindrical discs, Ø50 mm, projecting 15 mm. Arrange them in a precise 2×2 grid; centers at X=50/150 mm from the left and Z=50/150 mm from the bottom, giving 100 mm horizontal and vertical spacing. Overall size: 200 mm wide, 215 mm deep, 321.3 mm high. No rounded cube corners, top/side studs, extra parts, text, logo, cable, feet, holes, patterns or deformation. This is not a LEGO brick. Keep the cube, globe and four discs as separable parts if supported. Place the base flat at Z=0. Geometry and proportions are more important than texture.
