I was trying out the new configuration and figuring out how much working area I would lose to my uprights.

Then I realized how to get nearly all of it back.  I'm going to modify the C1, probably so much it won't be the C1 anymore.

I'm changing the angles for the uprights, and moving the bottom mounts to be part of the stepper and spool mounts.

Let the math begin..

EDIT:  Math done.  I realized I can't totally negate one of the angles as I will lose structural integrity, but I picked a good value in between.  It will still be better than it is now.

Printing the first three parts.

EDIT 2:  Assembled.  I lost a whole lot more structural integrity than I had bargained for.  Thinking about it..
