Aww. I thought you built that rack :p
would not be hard though if you have a dryer where the back does not move though (brace on front in the vent braced on back with some strong magnets).
Most dryers I have seen though hte whole inside rotates.
Need to get "The Club" or some time of locking extension poles to mount inside the dryer, strap a board to it and let it "spin dry" with some low heat
