Instructions
Just print the parts list and snap them together. I print all of these parts with one extra shell and zero infill, which works beautifully on my TOM. I recommend using Multiply to print four of each gear at once, and Cool to make sure the pins come out well.
UPDATE: The new gear pieces all start with 'B', and correspond to cubeGears3.scad. The pin tolerance worked great for me the first time, but if you have trouble, you can just print out new pins, perhaps scaled slightly. The short pins are for the small faces on the center block and the long pins are for the large faces. The pins should fit tightly into the center block and loosely into the gears so they spin freely.
The SCAD file is fully parametric, so feel free to adjust as desired.
UPDATE: Just added two plates for those of you who don't like to use the multiply feature. These are courtesy of Nick Starno.
