MK8 dual extruder for Prusa / Mendel
cults3d
Years ago I built a dual extruder for my printer and now I'm eager to share it with others, so they can enjoy the same benefits. The extruder relies on two Nema motors for its operation. Fan ducts don't require any external fan - they use the ones already attached to the hot end's heat sink instead. https://www.youtube.com/watch?v=pyxolriGxsk Initially designed for Prusa i2, this design can be easily modified to work with Prusa i3 as well. I used PLA plastic at a 0.3 mm layer height and infilled it with either 20% honeycomb or rectilinear patterns.
