The place that snapped off is the plastic right under the two screw heads which usually tend to be under a lot of pressure, especially if the person assembling it overtightened the screws. It doesn't matter how sturdy your trackers are when there are two weakpoints that'll always fail. I see a lot of these "plastic fastened together with screws" fail in modern electronics unless they're reinforced with some steel.
