This is waist belt buckle. It can be use with leather belt, fabrics belt and rubber belt. It can be 3d print and manufacture by iron cast mold. 3d editable STEP file also attached. You can weild pivot pin of the buckle after iron casting, then you can put belt pin. Should be use metal type materials to make it.

Custom size and design possible. You have to contact with me for this.
