Mimimalist Chess Set with magnet

I remixed Devanopolis' wonderful Chess set to incorporate a hidden magnet holder (bottom cup).  I extended the bottom of each piece to allow for a threaded insert in the bottom.  The Bottom Cup will hold a standard size 12mm magnet (possibly 2).  This will allow for it to stay better on a magnetic chess board, as well it adds some additional weight to the pieces.  

The bottom cup is designed to accept a large flat head screwdriver to assist with installation. The cup also has a small hole in case you need to extract the magnet.  Simply push in a small paper clip to release the magnet from the holder. The cup with magnet should screw in flush with the bottom of each piece or slightly recessed.
