{"data":{"id":"24589","slug":"animated-mechanisms-kit-blast-door-iris-52e784c6","title":"Iris blast door with six blades (Animated Mechanisms Kit)","summary":"Six overlapping steel blades hinged around a bezel ring close a 2.2 m circular portal cut through a wall bay. Each blade swings outward on its own pin.","description":"A 2.2 m diameter portal cut through a 3 m wall bay with a true round bore, a 0.48 m wide bezel ring on each face and six hinge bosses. Six tapered blades are stacked 38 mm apart in depth so they overlap without clashing, and sweep behind the bezel when open. Overall size 3 x 3.2 x 0.67 m in metres, +Y up, +Z forward, resting on y=0. Nodes `blade0` to `blade5` pivot on their own hinge pins on the bezel ring, every axis parallel to Z. Clips: `open` swings all six blades 62 degrees clear of the bore over 1.2 s, `close` returns them. Node TRS animation on named nodes only; no skinned rig, skeleton, collision or navigation data.","status":"published","url":"https://3dassets.dev/assets/animated-mechanisms-kit-blast-door-iris-52e784c6","cdnUrl":"https://cdn.3dassets.dev/assets/24589/v1/model.glb","downloadUrl":"https://3dassets.dev/download/animated-mechanisms-kit-blast-door-iris-52e784c6","thumbnailUrl":"https://cdn.3dassets.dev/assets/24589/v1/thumb.webp","posterUrl":"https://cdn.3dassets.dev/assets/24589/v1/poster.webp","blurhash":"U4BN7v_200I_Kn%i$uMb-OkB4:MxtR_N%200","category":{"slug":"buildings","title":"Buildings & Architecture"},"tags":[{"slug":"modern","title":"Modern"},{"slug":"low-poly","title":"Low Poly"},{"slug":"animated","title":"Animated"},{"slug":"modular","title":"Modular"},{"slug":"kit","title":"Kit / Set"},{"slug":"interior","title":"Interior"}],"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":67152,"triangles":1192,"vertices":3576,"meshes":11,"materials":5,"textures":0,"animations":["open","close"],"boundingBox":{"min":[-1.4999969705007488,-0.00004242077588291135,-0.37004302726663396],"max":[1.4999969705007488,3.200000047683716,0.29995505260436917]},"sizeMeters":[3,3.2,0.67],"hasDraco":false,"hasMeshopt":false,"hasKTX2":false,"extensionsUsed":["KHR_mesh_quantization"]},"aiGenerated":true,"aiModel":"Claude Fable 5.1","downloads":0,"publishedAt":"2026-09-07T20:26:57.459Z","updatedAt":"2026-09-07T20:26:57.587Z","usage":{"threejs":"import { GLTFLoader } from 'three/addons/loaders/GLTFLoader.js'\nimport { AnimationMixer } from 'three'\n\nlet mixer\n\nconst loader = new GLTFLoader()\nloader.load('https://cdn.3dassets.dev/assets/24589/v1/model.glb', (gltf) => {\n  scene.add(gltf.scene)\n  mixer = new AnimationMixer(gltf.scene)\n  mixer.clipAction(gltf.animations[0]).play()\n})\n\n// Call from your render loop; deltaSeconds is time since the previous frame.\nfunction updateAssetAnimation(deltaSeconds) {\n  mixer?.update(deltaSeconds)\n}","r3f":"import { useGLTF, useAnimations } from '@react-three/drei'\nimport { useEffect } from 'react'\n\nexport function IrisBlastDoorWithSixBladesAnimatedMechanismsKit(props) {\n  const { scene, animations } = useGLTF('https://cdn.3dassets.dev/assets/24589/v1/model.glb')\n  const { actions, names } = useAnimations(animations, scene)\n  useEffect(() => {\n    const action = actions[names[0]]\n    action?.reset().play()\n    return () => { action?.stop() }\n  }, [actions, names])\n  return <primitive object={scene} {...props} />\n}\nuseGLTF.preload('https://cdn.3dassets.dev/assets/24589/v1/model.glb')","modelViewer":"<model-viewer src=\"https://cdn.3dassets.dev/assets/24589/v1/model.glb\" alt=\"Iris blast door with six blades (Animated Mechanisms Kit)\" camera-controls auto-rotate autoplay></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/24589/v1/model.glb\n# Metres and +Y up are converted to Blender's Z-up scene automatically.\n# Clips arrive as actions; play them from the Dope Sheet > Action Editor.","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)\nvar player := model.find_child(\"AnimationPlayer\", true, false) as AnimationPlayer\nplayer.play(player.get_animation_list()[0])","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/24589/v1/model.glb\")) await gltf.InstantiateMainSceneAsync(transform);\n// Clips import as legacy AnimationClips on the root; GetComponent<Animation>().Play() starts the first."}}}
