I generally try to have a solid ring of material around the outside of the gearbox, so the bolts aren't cantilevered just on the ribs. You also don't want a snap ring groove right on the output axle after the gearbox like that, it'll create a stress concentration and greatly reduce the side load required to snap the output shaft.
