modular cosmetic device 3d model

Create a realistic industrial design 3D model of a modular cosmetic device called “Bibbity Bobbity Boo Nail Wand.” The object is a straight vertical stack of four cylindrical modules forming one smooth wand. Total height about 175 mm, diameter 29 mm. The bottom three modules are nail polish bottles with rounded cylindrical bodies, glossy cosmetic plastic, and short smooth caps containing nail polish brushes. Each cap has a flat circular top with hidden internal screw threads so another bottle can attach, meaning the cap of one bottle screws into the base of the next module, forming a continuous stack. Bottles represent base coat, color polish, and top coat with visible gel inside. The top module is a UV LED curing cap, cylindrical with a rounded dome tip, twist-to-activate light, recessed LED lens, and a small side USB-C charging port. All surfaces smooth, symmetrical, realistic cosmetic packaging.
