MK8 fan separator (improves printing)

cults3d

This simple thing will exponentially improve your prints and you will not have jams inside the barrel. This type of direct extruder (MK8), does not properly perform the thermal break in the barrel and on top of that it has a useless heatsink interrupting the air flow, with a laughable orifice. The separator lets air flow into the extruder and largely prevents heat from spreading upwards.
