It features and all stainless steel hot end that is precision machined to tightly screw together to prevent any leaks.  It gets rid of the Nichrome wire heater and replaces it with two power resistors.  The resistors draw a lot of power an must be used with a relay board.

The feeder uses the MK5 drive gear that has been available for while and gets rid of the idler wheel.  Instead, it uses a thumbscrew adjustable Delrin plunger.   he feeder uses the same DC motor as the MK4, but there is a NEMA 17 pattern for the planned upgrade to a stepper.

The design is of course on Thingiverse.  It is for sale and in stock at the store for $189.
