because team 1557 was thinking about new trains and we wanted to change the gear ratios from 12-1 to something lower

Yes, we used a few gears from the toughbox and a few gears from the AM supershifters (both of which we had lying around, you can buy the individual gears online). We then simply CNC'd new front and back plates for use of the new gears to press the front and back plates into. Like the toughboxes, we used lexan for the motor side, and 1/4" aluminum for the mounting/output side.
The ultimate ratio was around 7.8:1, much higher than the toughboxes, and slightly higher than the high speed of the supershifters. They have worked perfectly without a hitch. They took an evening to design, 2 days or so to CNC 4 perfect plates, and another day to assemble and break in.
Do you have any specific questions?
