Snapping Multiple Game-object to another in Unity 3D

Question

I have managed to snap my game object to the bottom of another game object, but once I have instantiated a second game object, it doesn't snap to the instantiated game object. I want to be able to have the instantiated game object to snap at the bottom of another instantiated game object once it has been loaded, similar to a daisy chain. Currently, it will only snap to the original "bottom" game object but not the second. Any suggestion?

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class SnapToMe : MonoBehaviour
{
    public GameObject target = null;
    public float snapDistance = 2f;

    void FixedUpdate()
    {
        if (target == null) return;

        if (Vector3.Distance(transform.position, target.transform.position) <= snapDistance)
        {
            target.transform.parent = transform;
            target.transform.localRotation = Quaternion.identity;
            target.transform.localPosition = Vector3.zero;
            target.GetComponent<DragObject>().enabled = false;
        }
    }
}

public void LoadDrillString()
{
    if (!isCreatedDrillbit)
    {
        GameObject instance = Instantiate(Resources.Load("Drillstring-2", typeof(GameObject))) as GameObject; 
        GameObject TipSnapPoint = GameObject.Find("Bottom");
        SnapToMe tipsnapper = TipSnapPoint.GetComponent<SnapToMe>();
        tipsnapper.target = instance;
        tipsnapper.snapDistance = 2f;
    }
}
