Worked on the mirror arm, a lot.  Most dimensions are now direct multiples of the nozzle diameter, the camera area is based on rotating a model of the camera, there is a mask beyond the top of the main mirror now, and I added....

Wings.

The wings give me a place to snap on a little bracket. The little bracket will let me mount some strip lights at the appropriate height and angle for the bottom vision.  It can't be printed as one piece as the lights would need to be below the bed here and I'm not giving up the strength I'm getting from printing this flat.

I'm doing this because it will just be easier and less problematic to have proper lighting instead of trying to get backlighting of the parts working, for now at least.

The hood over the main mirror is a single width extrusion.  It printed great, and the weight is now back down to 3.1 grams.

Going to paint it camo black tomorrow and make some new mirrors.
