Hard-surface industrial product design aesthetic. Clean manifold geometry, watertight mesh, no overlapping faces, no interior geometry, wall thickness minimum 2mm throughout. Export as print-ready STL with units in millimetres. No textures, no colours — pure white PLA prototype shell. Separate the front panel and back shell as two interlocking snap-fit parts for assembly.i want
