New part day.

Made the changes to eliminate the part light ring and moved the main light ring out of the camera's FOV.

Mirror arm width was tweaked now that I don't have to clear the light ring gap.  This allows for rotation of larger parts.  I think I'm up to rotating 24mm parts at up to 14mm of depth now, but I'll check for sure once I have it assembled.  

The end mirror is 8mm wider and 4mm taller than it was before to reflect more light onto the part.

I also updated the mask in front of the camera to be three slits with a gap, instead of a smooth 'light pipe' like it was before.

Body lost 1mm of height overall for additional board clearance, the camera mount was tweaked a little, and the light ring mount was moved down since the new ring spans the body to get out of the camera FOV. 

The new part light ring.  It was considerably harder to design that the other rings actually.  To get the rounded ends more than doubled the code size..  :)

Printing the ring and arm first, and we'll see where the camera FOV ends up before I print the body again.
