Reduced side plates to 3/8", made the top plate and the steering pulley their own separate pieces, and made slots in the plates to slide the CIM into a position to pull it out. Weight as pictured is 5.8lbs.
You should round off the corners of the pockets. This will distribute the stress over a larger area, and be eaiser to machine.
As usual, questions and feedback are much appreciated 
What is your overall reduction between the CIM and the wheel, and what Diameter is the wheel? Also what are you using to transfer the power from the CIM (belt, chain, etc)?
I second this. Any sharp internal corners create very unwanted stress concentrations.
As this is clearly not coaxial, what are you planning for the power cable management?
Is there any significant advantage to having the wheel so wide? I understand you want this to be a pushing bot, but there are definitely diminishing returns when it comes to wheel surface area and friction.

Thank you much Gus!
So a friend pointed out that I did not take the CIM shaft into account when designing the “CIM removal slot”. This sparked two things; lots of swearing and a complete redesign of the left side plate. Photos later.
Edit: there are also no square corners in the lightening pattern as of now
Posting to bump my request from the other thread for a half section view that shows the bearing setup.
I cannot seem to figure out how to put an image from my ipad into a reply. I could email it to you?
Sure, and then I will post it here for you if that is okay.
Yes please!
