Mk III and MK V Decisions

I have made some decisions regarding the Mk III and Mk V designs. 

  1. Due to the success, of the Mk IV, I am going to stop production of the Mk III hot-ends.  The Mk IV has been shown to successfully extrude PLA as well as the Mk III.
  2. The Mk V design is no longer going to include an internal aluminum heat-sink.  The Mk IV has proven that it isn't required and I would rather lean towards design simplification as per one of the original goals.  Adding the internal heat-sink and spacer only unnecessarily complicates the design.
  3. The Mk V will be improvements built upon the Mk IV.  Some possibilities include shortening the brass that projects into the nozzle holder, shortening the nozzle holder, and adding additional cooling to the nozzle holder.
