{"data":{"id":"24617","slug":"animated-mechanisms-kit-crank-flywheel-30a55803","title":"Crank and flywheel with connecting rod (Animated Mechanisms Kit)","summary":"Heavy six spoke flywheel on bearing pedestals driving a crank, connecting rod and crosshead along a painted bedplate with an amber hazard band at the end.","description":"A 1.9 m by 3 m bedplate and painted housing carry two bearing pedestals, a 1.2 m six spoke flywheel with a rim band and a crank web opposite it. The connecting rod runs to a crosshead sliding between two guide bars into a stuffing box. Overall size 1.9 x 2.04 x 3.02 m in metres, +Y up, +Z forward, resting on y=0. Nodes `flywheel` and `crank` turn on the same shaft axis at y=1.44, z=-0.3; node `crosshead` slides on Z; node `rod` pivots on the crosshead pin and slides with it. Clips: `spin` turns the flywheel one full revolution over 3 s, driving an exact crank and slider cycle. 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-crank-flywheel-30a55803","cdnUrl":"https://cdn.3dassets.dev/assets/24617/v1/model.glb","downloadUrl":"https://3dassets.dev/download/animated-mechanisms-kit-crank-flywheel-30a55803","thumbnailUrl":"https://cdn.3dassets.dev/assets/24617/v1/thumb.webp","posterUrl":"https://cdn.3dassets.dev/assets/24617/v1/poster.webp","blurhash":"U6AAm=%K00NG4T9Fo$xu00%L_NenyY%hadt7","category":{"slug":"props","title":"Props & Furniture"},"tags":[{"slug":"modern","title":"Modern"},{"slug":"low-poly","title":"Low Poly"},{"slug":"animated","title":"Animated"},{"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":43448,"triangles":768,"vertices":2304,"meshes":8,"materials":4,"textures":0,"animations":["spin"],"boundingBox":{"min":[-0.9500716807448104,-0.00008859884736378554,-0.8999999761581421],"max":[0.9500716807448104,2.039999964237213,2.120023394313487]},"sizeMeters":[1.9,2.04,3.02],"hasDraco":false,"hasMeshopt":false,"hasKTX2":false,"extensionsUsed":["KHR_mesh_quantization"]},"aiGenerated":true,"aiModel":"Claude Fable 5.1","downloads":0,"publishedAt":"2026-09-07T20:27:03.911Z","updatedAt":"2026-09-07T20:27:04.018Z","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/24617/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 CrankAndFlywheelWithConnectingRodAnimatedMechanismsKit(props) {\n  const { scene, animations } = useGLTF('https://cdn.3dassets.dev/assets/24617/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/24617/v1/model.glb')","modelViewer":"<model-viewer src=\"https://cdn.3dassets.dev/assets/24617/v1/model.glb\" alt=\"Crank and flywheel with connecting rod (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/24617/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/24617/v1/model.glb\")) await gltf.InstantiateMainSceneAsync(transform);\n// Clips import as legacy AnimationClips on the root; GetComponent<Animation>().Play() starts the first."}}}
