[Help] How to create relation

I have the following relationship between models:

class Product extends \Common\Models\ModelBase {

    public $id;
    public function initialize()
    {
        $this->hasMany('id', 'Common\Models\ProductProperties', 'product_id', array('alias' => 'ProductProperties'));
        $this->hasManyToMany('id', 'Common\Models\ProductProperties', 'product_id', 'property_id', 'Common\Models\Properties', 'id', array(
            'alias' => 'Properties',
            'params' => ['order' => 'sort_id']
        ));
    }
}

class ProductProperties extends \Phalcon\Mvc\Model {

    public $id;
    public $product_id;
    public $property_id;

    public function initialize()
    {
        $this->belongsTo('product_id', 'Common\Models\Product', 'id', array('alias' => 'Product', 'reusable' => true));
        $this->belongsTo('property_id', 'Common\Models\Properties', 'id', array('alias' => 'Properties', 'reusable' => true));
    }
}

class Properties extends \Common\Models\ModelBase {

    public $id;
    public function initialize()
    {
        $this->hasManyToMany('id', 'Common\Models\ProductProperties', 'property_id', 'product_id', 'Common\Models\Product', 'id', array('alias' => 'ProductProperties'));
        $this->hasMany('id', 'Common\Models\PropertiesParams', 'property_id', array(
            'alias' => 'Params',
            'params' => ['order' => 'sort_id']
        ));
    }
}

class PropertiesParams extends \Common\Models\ModelBase {

    public $id;
    public $property_id;
    public function initialize()
    {
        $this->belongsTo('property_id', 'Common\Models\Properties', 'id', array('alias' => 'Properties', 'reusable' => true));
    }
}

So, I have Product, Properties and Properties Params. For Product I can choose custom Properties. I need to have possibility to choose custom Property Params for Product. I need to create new table ProductPropertiesParams and whan kind of relation for this I need to use? I want to sometsing like this:

$product = Product::findFirst($id);
$product->Properties // properties for product
$product->Properties->Param // it's work's right now, but it's params for Properties
// I need:
$product->Properties->ProductParams

How to implement this?

Well if this custom property params can be for many products then you need many to many. If they will be only to one product - then many to one.
