Of course, just my opinion; the gear does look closer than the one on my gearbox did to the bearing.
Remember to put some kind of protection over the gears like polycarbonate, else wires will get stuck in there, as well as fingers.
It looks like there are two screws on the bottom of the gearbox that don't go all the way through the nut. Consider switching to thinner locknuts or lengthening the screw just in case.

I'm not understanding something here then; if it wasn't bent, how could the gear possibly come out of alignment? Were the tolerances bad? Were your bearings messed up? Were the bearings really close together?
