About this model
This crankshaft 3D model turns the rotating core of an inline four into a clean showpiece. Five polished main journals and four polished crank pins catch the light against dark forged webs, with pins one and four on top and two and three below, as in a real four cylinder engine. Every web carries a rounded counterweight, and small oil holes sit on the journals. The front ends in a toothed timing sprocket, a snout with a key and a threaded nose, while the rear carries a flywheel flange with six bolt holes. The shaft lies on its counterweights, so it rests safely on a bench or a parts shelf. It is 59 x 12 x 17 cm with 7,604 triangles and 2K PBR textures and pairs well with the engine piston.
Good for
- Engine teardown display
- Machine shop or workbench prop
- Car building or repair game

Engine import notes
Unity GLB · FBX
Import the GLB with the glTFast package or use the FBX. 1 m in the file = 1 Unity unit.
Unreal Engine FBX
Use the FBX. The model is built in metres. Unreal works in centimetres and converts on import, so it arrives at real size (0.17 m = 17 cm).
Godot 4 GLB · FBX
Drag the GLB into the FileSystem dock. Godot 4 imports it directly, with materials. The FBX works too (Godot 4.3+ imports it natively).
Blender BLEND · GLB
Open the .blend directly, or import the GLB via File › Import › glTF 2.0.
