  We propose a simple gauge-mediated supersymmetry breaking model in which
suitable soft breaking masses are dynamically generated without relying on a
messenger sector. This model is constructed as an extention of the 3-2 model
and needs no fine-tuning of parameters. The dynamical supersymmetry breaking
sector contains non-renormalizable interactions and vector-like fields.
Non-renormalizable terms are characterized by the couplings of O(1) in units of
the Planck scale. The vacuum of this model conserves the color and electro-weak
symmetry.
