Bounding Box Cage

Bounding box cage, twelve thin smooth round bars 0.01 m across on a box's edges, width, height, depth 0.5-4 m (default 1) moving bars without resizing them, a small sphere handle on each corner glowing in the accent. Hover swells the handles.

风格：low-poly, flat-shaded vertex colors, no textures, 2 materials: the shared opaque one plus a distinct surface (glass, water or chrome), which stays its own mesh through mergeAssets rather than merging into the rest; shares palette and scale with its kit
