From what I can tell, the back plate of the gearbox was loose allowing the output shaft to move slightly. The output shaft was torqued to the side and the gears meshed at and angle with each other, and now one of the gears has a ridge eaten out of teeth. We tried interchanging different gears from the toughbox because the ratios are the same, but the gears have different thicknesses and have different sized hex so it didn't work.
We have a toughbox and a banebots 12 : 1 planetary gearbox: (

that we would be willing to trade, so if anyone is interested in trading or selling just PM me and we can figure out shipping. We are in New York City just for reference.
Thanks,
