-The height of the module is excessive. More than 5-6 inches is too much. I see you have already elected to fix this.
-Where is the bevel gear and sprocket coming from? If it's the vex one, how are you making a 3/8" hex bore sprocket?
-Those gear teeth up top look cool, but you may not be able to make them even with a 4th axis CNC. Gear tooth cutters often have a very large radius, so it could be difficult to cut small gear teeth there.

As a side note, put all your encoders in CAD. It will make life so much easier. Also put motors, mounting, etc. into the CAD.
The height has already been modified in my most recent update to the module (will post photos a little later)

The bevel gear is the vex one and from the model it looks possible to bore it out to 1/2in and then broach a 1/2in hex into it which is what I am hoping for. If not I will need to rethink that portion.

The "gear" pattern at the top is currently meant to interface with an htd 5mm belt allowing the module to turn. I will be making some cuts within the next few days to see if it is possible to make a cog in house that will effectively mesh with such a belt using our resources at hand.

As for the encoders, motors, mounting, etc. those are all things that are yet to come. I have begun sketching some layouts for the other components but for the moment this is what I've accomplished these past two days.
