PowerWheels gearbox.

SummaryTrying to remake my kids powerwheels gearbox, I want to add another motor.InstructionsWell, Its a work in progress and since I have no engineering degree and I base everything off of Google searches it's taking me a while, even before my first print. Please let me know if you are interested and if you could help with the design. I have no clue what is the gear ratio, and no clue if it will even work properly. Here is a work in progress file maybe the comunity could help me finish this project.
