There are a few commercially available options but I grabbed a piece of aluminum tubing (handlebar or seatpost trimmings aren't too hard to find if you ask at an LBS), some bar plugs, a bolt, and a lock washer.
Run the bolt through a lock washer (to keep the mount from spinning) and through one of the bar plugs and then put the tube over that, and the cap on the other end.
