I believe you are required to pass the database configuration when creating a new custom model. So, you shouldn't load it as a Codeigniter model, since it is an external class or library.

Agreed with @dlaynes statement.

Look at the code below. This additional function has to be added on your controller.

 private function _getDbData(){

    return [
        'adapter' => [
            'driver' => 'Pdo_Mysql',
            'database' => 'db_name',
            'username' => 'db_username',
            'password' => 'db_password',
            'charset' => 'utf8'
        ]
    ];

}


public function setProject()
{
    include(APPPATH . 'models/Cust_proj.php');
// $this->load->database();
// $this->load->model('cust_proj');
    $model = new \Cust_proj($this->_getDbData);
    $crud->setModel($model);
    $crud->setTable('tbl_data_project');
}
