Looks like a great looking gearbox, our team developed something similar last year. We manufacture the plates from polycarbonate and the gears from acrylic and have donated them to a lot of teams, especially those outside of North America who have problems getting parts.

What reduction is it? We found a single stage 7.5:1 spur reduction to be ideal for running intakes, conveyors and wheels in our testing.
The motors don't have a lot of power but they are extremely reliable and unkillable, coupled with a decent gear reduction, Plenty of different mounting holes and a 1/2" hex output shaft they can be very useful.
We have a 3D printed design and I'll happily share it with you once I get back to my PC after kickoff tomorrow.
