  "descriptionEn": "One freestanding ground-anchored goal for an outdoor basketball court, with a nominal 3.05 m ring height, 1.80 × 1.05 m opaque backboard, open hoop and diamond net, rear frame, cantilever arms, post, gussets and anchors. No ball, court or opposite goal. Static decorative geometry with no sporting-standard certification, load calculations, tip-over or playground-safety validation. For games and visualization; not validated for manufacture, structural engineering or 3D printing. Bounding dimensions (X×Y×Z): 1.810 × 4.000 × 1.960 m; 18,140 triangles. Metres, Y-up, horizontally centered placement origin with minimum Y=0, not an articulation or wall-mount pivot. Includes overlapping component UV0 and constant-color PBR materials, with no image textures, unique UV2, colliders, LOD, rig or runtime behavior. Static visualization only; Unity/VRChat editor and runtime tests have not been performed. STL uses metre-valued Y-up coordinates and contains geometry only, without color, materials, UVs or hierarchy.",
