ice cube 3d model

3D printable perfume cap cover only, no bottle. Create one solid chunky frozen-ice cap, like a compact piece of carved glacier ice, not amethyst, not a crown, not spikes. External size: 45 mm tall, 35 mm wide, 30 mm deep. Shape should be asymmetrical, faceted, icy, smooth-edged, with thick broken-ice planes and a luxury niche perfume aesthetic. The top and sides must be closed solid surfaces. The bottom must be flat. Important: add a hidden blind cylindrical cavity ONLY on the underside/bottom, centered on the vertical Z axis. Cavity size: 20 mm diameter, 28 mm deep, open only at the bottom, closed at the top. This cavity fits over a standard perfume cap. Do not create any front-facing hole, side hole, ring, tunnel, or visible circular opening. Minimum wall thickness 3 mm. No thin fragile spikes, no radial crown, no explosion shape, no leaf shapes. Solid watertight mesh, suitable for SLA/resin or FDM 3D printing and silicone mold making.
