Quick Change Gear Box

Update:
55 Tooth gear for 1:1 quick change.

Update:
Rear gear cover and side axle cover added.
Will have some more spur gears soon.


I have been playing with this idea for a couple weeks now.
I will have more for it,
The bevel gears are 2:1
The rear gears will be replaceable with interchangeable gears for more reduction.
The hex hubs and differential gears are from Banebots, the T40 series.
I will design extra gears for different ratios.
I will not print it till I"m done.
I"m trying to keep it with off the shelf parts.
I am still preferring a 3:1, 4:1 ratio with the bevel gears. Looking for them.
Maybe someone can run with it.
I will update when possible.
