Fan problem.. deferred

We got the fan in there last night - trusty Dewalt driver by the ready, and 4 inch screws to go right into the beam. That sucker's not going anywhere, but there remains a slight problem.. the hole from the prior fan box. That's going to be a bit of an eyesore for a bit.  Probably next year if we get to do the master bathroom, we'll patch it with some drywall.  For this week's visitors, this will do.
