I got sick of having an over flowing bin on overnight prints so I sliced and diced a couple of parts into a poop chute that a plastic bag can be attached to. Note that it is back heavy so you can either stick velcro or bluetak it to your table. The other option is to add a pause to the gcode before the top layer prints on the bin and glue a bit of steel or something heavy in the cavity before it gets closed up. You also need to glue the chute to the bin.
