UPDATE:
Now that school is out, I have more time to work on this project (at least for a couple weeks until my internship begins).

So, getting these made via CNC mill from aluminum will be VERY expensive. But who cares if its made from aluminum. I mean, its a tranny, and as far as the chassis is concerned, it does little to strengthen the vehicle. (which is why no one really uses the few avaible alum trannies for the savage)

I have access to a rapid prototyping machine that is much more practical.

I will be churning out one two for myself this coming week. I am wondering if anybody would be interested in a plastic version. A few changes may be made to the design you see now, but overall, it will be the same. Instead of tapping the holes, i will make holes ready to be tapped, but since its plastic, I will let the screw thread itself in. Machine screws will work fine, plastic screws are not neccesary. (I have always found the machine screws to be more snug than actual plastic screws anyways.)

Also, since rapid protoype makes it easier to do curves (like things curved in multiple dimensions), I may add some extra stuff (or remove) to make assembly easier. I can also easily customize them for different motors/pinion sizes if needed.

For low kv motors, I may offer a version that sits the motor a tad higher (like .125" or .25") to allow larger pinions (15+ teeth)
