Dimensions 0.72 x 3.00 x 0.64 m (X x Y x Z). Origin at the duct centre on the underside of the bottom flange; the access panel faces -Z. Metres, +Y up, +Z front, ground contact at y=0. Flanges bolt to the next riser segment at the run-end ports for a continuous shaft. Connectors: bottom (run-end), top (run-end). Neutral greybox palette for prototyping before art exists. Static geometry; no skinned rig, collision or navigation data.","status":"published","url":"https://3dassets.dev/assets/modular-greybox-architecture-kit-service-riser-duct-3m-7e9da350","cdnUrl":"https://cdn.3dassets.dev/assets/22923/v1/model.glb","downloadUrl":"https://3dassets.dev/download/modular-greybox-architecture-kit-service-riser-duct-3m-7e9da350","thumbnailUrl":"https://cdn.3dassets.dev/assets/22923/v1/thumb.webp","posterUrl":"https://cdn.3dassets.dev/assets/22923/v1/poster.webp","blurhash":"U08Ntl.80000o#xuoIDiNFM{nm.8t8t7s-Mx","category":{"slug":"roads-infrastructure","title":"Roads & Infrastructure"},"tags":[{"slug":"modern","title":"Modern"},{"slug":"low-poly","title":"Low Poly"},{"slug":"kit","title":"Kit / Set"},{"slug":"modular","title":"Modular"}],"license":{"slug":"cc0-1.0","name":"CC0 1.0 Universal","url":"https://creativecommons.org/publicdomain/zero/1.0/","attributionRequired":false},"contributor":{"username":"3dassets","name":"3D Assets","url":"https://3dassets.dev/u/3dassets"},"stats":{"fileSize":14460,"triangles":264,"vertices":792,"meshes":2,"materials":2,"textures":0,"animations":[],"boundingBox":{"min":[-0.35999633777886286,0,-0.2598950139432168],"max":[0.35999633777886286,3,0.3798950187115884]},"sizeMeters":[0.72,3,0.64],"hasDraco":false,"hasMeshopt":false,"hasKTX2":false,"extensionsUsed":["KHR_mesh_quantization"]},"aiGenerated":true,"aiModel":"Claude Fable 5.1","downloads":0,"publishedAt":"2026-09-07T20:02:33.916Z","updatedAt":"2026-09-07T20:02:34.035Z","usage":{"threejs":"import { GLTFLoader } from 'three/addons/loaders/GLTFLoader.js'\n\nconst loader = new GLTFLoader()\nloader.load('https://cdn.3dassets.dev/assets/22923/v1/model.glb', (gltf) => {\n  scene.add(gltf.scene)\n})","r3f":"import { useGLTF } from '@react-three/drei'\n\nexport function GreyboxServiceRiserDuct3MModularGreyboxArchitectureKit(props) {\n  const { scene } = useGLTF('https://cdn.3dassets.dev/assets/22923/v1/model.glb')\n  return <primitive object={scene} {...props} />\n}\nuseGLTF.preload('https://cdn.3dassets.dev/assets/22923/v1/model.glb')","modelViewer":"<model-viewer src=\"https://cdn.3dassets.dev/assets/22923/v1/model.glb\" alt=\"Greybox service riser duct 3 m (Modular Greybox Architecture Kit)\" camera-controls auto-rotate></model-viewer>","blender":"# Blender 4.x: File > Import > glTF 2.0, or from the Python console after downloading the file.\nimport bpy\nbpy.ops.import_scene.gltf(filepath='model.glb')  # from https://cdn.3dassets.dev/assets/22923/v1/model.glb\n# Metres and +Y up are converted to Blender's Z-up scene automatically.","godot":"# Godot 4: copy model.glb into res://models/ and the editor imports it as a scene.\nvar packed := load(\"res://models/model.glb\") as PackedScene\nvar model := packed.instantiate()\nadd_child(model)","unity":"// Unity: import model.glb with glTFast (Package Manager: com.unity.cloud.gltfast) and drag the prefab in,\n// or load it at runtime straight from the CDN:\nusing GLTFast;\nvar gltf = new GltfImport();\nif (await gltf.Load(\"https://cdn.3dassets.dev/assets/22923/v1/model.glb\")) await gltf.InstantiateMainSceneAsync(transform);"}}}
