CD-Rom Motor Pump

This is a derivative of Madox's Mini Centrifugal Pump, http://www.thingiverse.com/thing:4839
I simplified the design and adapted it to be printable on a makerbot without support material.
I also modified it so that the motor from an old CD-Rom drive can run the pump. These motors are all about the same size, and anyone who likes to take things apart more then likely has a few laying around.
In the photos I am powering a 6 volt motor with a 3.5 volt battery. I imagine more power would equal more water moved.
