bedside clock spherical shell

Create a hollow spherical enclosure for a modular bedside clock. Overall outside diameter: 165 mm. Outside radius: 82.5 mm. Uniform wall thickness: 3 mm. Material: FDM-printed PETG. Create a spherical shell with two circular openings on opposite sides of the sphere, aligned along a common front-to-rear axis. Front opening: - Approximately 85 mm diameter. - Incorporate a reinforced circular mounting collar. - Provide a flat annular seating surface for a removable front bezel. Rear opening: - Accommodate a removable acoustic pod with a 106 mm outside diameter and 128 mm outer trim ring. - Incorporate a reinforced circular mounting collar. - Provide a flat annular seating surface for a removable rear assembly. The two openings must be accurately aligned and centred on the same axis. Add reinforced mounting regions around both openings. Preserve the spherical exterior everywhere else. The shell will be covered in charcoal-grey fabric, so prioritise smooth transitions and avoid unnecessary external details. Do not generate the front bezel, speaker pod or pedestal. Generate only the hollow main shell. Keep the front and rear collar geometry as simple editable features. Bayonet slots can be added in a later refinement.
