The lights on this board are just stupid bright and can keep you awake on a bedside table, so I printed the bottom in black to knock the light down most of the way, and the top transparent.  With the phone on top, just enough of the blue "charging" light leaks out around the phone to give a nice effect.To assemble, put 4 drops of glue on the mount corners and set the board in.  Put a drop of glue on the back of the board and set the coil on top.  Put the cover in place and secure with a couple of screws.  I used sheet metal screws, I think #8, whatever fits the holes.
