perforated dome 3d model

three-dimensional perforated shell structure, freestanding object, neutral industrial artifact, curved volumetric form without recognizable anatomy, forward-projecting dome-like geometry, open interior cavity, no symmetry emphasis, no decorative motifs. Surface covered with dense and irregular field of circular holes of varying diameters, mixed with elongated slots and keyhole-shaped cutouts, non-uniform spacing, rhythmic but non-grid pattern. Material appearance: matte industrial polymer or composite sheet, medium thickness, slightly textured surface, subtle manufacturing marks, edges softly chamfered, corners rounded, no sharp points. Structural detailing: shallow reinforcing ribs, local thickening around clusters of perforations, corrugated undulations for stiffness, visible logic of load distribution, tool-like construction aesthetic. Perimeter defined by a thickened rim with occasional notches and scalloped segments, suggesting attachment and modification potential. Object appears modular, hackable,
