MMU2s IR Sensor Holder tower (strengthened)

I kept getting filament runouts on a non-MMU2 print... then I noticed the stock IR filament sensor tower (for the MMU2s) had split out the side that was thin. That side was only one perimeter thick, all the way to the edge, and split quite easily, when the rest of the print was solid. I decided to strengthen just the back edge, to keep it from tearing out if/when the sensor is pulled, probably from one of the times I had to take the tower off for servicing, but who knows. I'm amazed they thought that one perimeter was good enough for something that needs to be rock solid.
