I am just wondering after C4 and the MR helmets which are available that we can finally get some definitive measurements on the ear pieces and stalk dimensions. All the drawings we have seem to lean towards a tapered stalk but looking at the C4 pictures the stalk seems to have a rectangular cross section. Maybe anyone who has seen these in person could shed some light for us scratchbuilders as to the dimensions of the stalk and ear pieces and come up with a set of definitive drawings in AutoCad or Solidworks for the actual screen used helmets. I posted this in the Sarlacc Pit also under a previous thread.
