Free 3D model for medieval, crafting and village game scenes in Unity, Godot, Unreal, three.js and Blender. Overall 1.22 by 1.13 by 0.84 m (X by Y by Z). Metre units, +Y up, the working face toward +Z, resting on y=0 with the origin on the footprint. Rigid node-transform clips: spin and tilt. No skinning. The crank throw and the connecting rod are modelled solid and stay where they are: a crank linkage needs a joint at each end and neither is reachable with one rigid node transform, so the stone turns and the treadle rocks independently. The water in the trough is a flat solid surface. No maker's names, marks or readable writing anywhere: every stamp and mark is an abstract shape.","status":"published","url":"https://3dassets.dev/assets/blacksmith-forge-and-armoury-blacksmith-forge-and-armo-d2dc5b62","cdnUrl":"https://cdn.3dassets.dev/assets/37585/v1/model.glb","downloadUrl":"https://3dassets.dev/download/blacksmith-forge-and-armoury-blacksmith-forge-and-armo-d2dc5b62","thumbnailUrl":"https://cdn.3dassets.dev/assets/37585/v1/thumb.webp","posterUrl":"https://cdn.3dassets.dev/assets/37585/v1/poster.webp","blurhash":"U28pM$~A0001-;s;MwI.00NF_3tm8_wH?vk?","category":{"slug":"weapons-tools","title":"Weapons & Tools"},"tags":[{"slug":"medieval","title":"Medieval"},{"slug":"realistic","title":"Realistic"},{"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":91036,"triangles":456,"vertices":1001,"meshes":7,"materials":4,"textures":2,"animations":["spin","tilt"],"boundingBox":{"min":[-0.5799999833106995,0.00002047514775038728,-0.47001142475063806],"max":[0.6399903866266947,1.1299999940395355,0.36999998092651365]},"sizeMeters":[1.22,1.13,0.84],"hasDraco":false,"hasMeshopt":false,"hasKTX2":false,"extensionsUsed":["KHR_materials_transmission","KHR_mesh_quantization","EXT_texture_webp"]},"aiGenerated":true,"aiModel":"Claude Opus 5","downloads":0,"publishedAt":"2026-09-12T05:41:03.846Z","updatedAt":"2026-09-12T05:41:03.960Z","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/37585/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 TreadleGrindstone12MBlacksmithForgeAndArmoury(props) {\n  const { scene, animations } = useGLTF('https://cdn.3dassets.dev/assets/37585/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/37585/v1/model.glb')","modelViewer":"<model-viewer src=\"https://cdn.3dassets.dev/assets/37585/v1/model.glb\" alt=\"Treadle grindstone, 1.2 m (Blacksmith Forge and Armoury)\" 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/37585/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/37585/v1/model.glb\")) await gltf.InstantiateMainSceneAsync(transform);\n// Clips import as legacy AnimationClips on the root; GetComponent<Animation>().Play() starts the first."}}}
