About this model
A clean spur gear 3d model with a real involute tooth profile. It has 36 teeth with module 3 and a 20 degree pressure angle, which gives a pitch diameter of 108 mm and an outside diameter of 114 mm. The steel rim carries the teeth with small chamfers, a blue painted web with six round lightening holes connects it to a wide steel hub, and the 25 mm bore has a proper keyway. Because the profile follows the standard formulas, the part meshes with any module 3 gear at a centre distance of 1.5 mm times the sum of both tooth counts. It stands upright on one tooth with the face toward the viewer. The complete wheel is a single rotor object whose origin lies on the axis. Size 11.4 x 3.6 x 11.4 cm, 7,952 triangles, 2K PBR textures. A ready assembled train is available as the Gear Set.

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 (0.11 m = 11 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.
