I took the little 12V muffin fan out of mine today to see what you were talking about. I just see a slight recess into a plastic hole, maybe ment to hold the wire connector.. As for enlarging the hole, I used a 3" hole-saw. It will be difficult to do it like that without a jig. I used (2) 1/2" boards sandwhiched together, drilled my 3" hole in it, then centered it on over the orig. hole, drilled holes where the tower sits to hold the jig in place and it seemed to work out great. As to drilling the hole in the plastic top, you can put the top back on and screw your jig back on and cut from the top down, or set the top in place and cut from the bottom up without using the jig. As for what to use inplace of the danby plastic thing that goes to the tower, I made one using a 3" aluminum duct connector and some electrical fixture box/thing that had the same diameter. I cut the two tabs out that were inside it with a dremel and slid that in place. The aluminum will be about an inch or so too long, so I just used some nippers and cut slits around the edges and folded them back. Then I caulked the opening around the bottom and made a rubber gasket to set ontop of the new sleeve. Here are some pics.
