About this model
Quiet running transmissions use slanted teeth, and this helical gear 3d model shows them clearly. The 28 teeth have an involute profile in the transverse plane with module 3 and run across the 34 mm face at a helix angle of 20 degrees, built as a true twisted solid instead of a texture trick. The pitch diameter is 84 mm and the outside diameter 90 mm. A steel rim with chamfered tooth ends sits on a yellow painted web with five lightening holes, and a long steel hub reaches out on the back with a 20 mm keyed bore. The gear stands upright on its teeth facing front. The rotor object turns around the gear axis. To run it against a partner you need a gear of the same module and helix angle with the opposite hand. Dimensions 9 x 5.2 x 9 cm with 16,812 triangles and 2K PBR textures.
Good for

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 (0.09 m = 9 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.
