A small model for dummy units in a projectile system

I need a model for some functions I'll soon make, the model should have nothing but have three attachment points: "0", "1", and "2" and a turneable bone related to the attachment points that could be called "pitch" or something.

The point of this model is that when making custom spells when you want stuff like moving special effects, you need to make an extra unit type, but that just got annoying after having 50 of them, with a model like the one I am talking about I would be able to use the same unit everytime. And with a turneable bone I will be able to make the missiles have arc and stuff.

About the positions of the attachment points : "0" should be at the same position as "origin" in the peasant model, "1" should be at "chest" and "2" should be at the same height as "overhead" in the peasant model.

The most important thing here is the turneable bone, since I already have a model with the attachment points
