Specifically where would you get the gears?
If you want to make your own gearbox, you could make two 3:1 sets; I'll use the Tetrix gears as an example - SDP-SI.com has a good selection of spur gears to use. Mount a 120 tooth gear to the motor output adapter, attach a 40 tooth gear to another 120 tooth gear and mount it 2.5 inches away, then attach a 40 tooth gear to your output on the same axis as the motor output shaft (doesn't have to be on the same axis but it simplifies the housing).
