This a 1:1 model of a basic brushless motor with a diameter of 28mm. All measurements, including the cable length, should be the same as the measurements of the real motor. They might however differ from the measurements of other motors in some places like the cables or the plugs. The holes on the front aren't threaded in the model, in the real motor they have an M3 thread. It is intended to be a design template so you can build your model around it in CAD.
