Add .blend file to the scene at runtime.

I made a 3d model with blender and imported it as mask.blend. Now - I’d like to add it to the scene the same way the drag&drop works, but through a few lines of code. I’ve tried creating an empty gameObject, then adding a meshFilter, etc. Nothing seems to work.
I’m using c#,
Thank you in advance.

Is this what you want?

using UnityEngine;
using System.Collections;

public class answer : MonoBehaviour {

	public GameObject blenderModel;
	public GameObject spawn;

	void Update () {
		if (Input.GetKeyDown ("e")) {
			Instantiate (blenderModel, spawn.transform.position, spawn.transform.rotation); //Spawns blenderModel at spawn's location

		}
	}
}
