Another way to go is to mod a round plastic food container with a 
snap-on lid that is microwave oven safe:  cut a hole in the bottom with 
a dedicated (to plastic cutting), conical soldering iron tip, glue the 
box to the chassis with silicone rubber, let cure for 24-hrs, cut a 
hole in the lid that will snap on over the anode.  //  note:  the 
typical air temperature that comes out of an anode cooler is about 
110ºF less than the softening point of such plastic.
