Ps3 Move Holder

here is a holder i made for the ps3 move. i made it with the thought that it could join onto the knex ps3 controller stand by whitestorm1000 . it isnt very stable unfortunately - it twists in the centre of the riser, so i would gladly appreciate any tips or advice on how to strengthen it.
