Hey everyone,

After building my i3v (with the help of this forum and its awesome members), I've had pretty good results with the smaller items I've printed. Like some, I've had my doubts about the printed extruder and its longevity and accuracy. Looking at my Printrbot, I'm wondering if the all metal extruder would be a good upgrade for our i3v's.

The extruder is considerably smaller and lighter than the current set up, and up to this point has been very reliable and consistent in the prints its produces, not to mention easier to load filament. From it's appearances, it seems it should mount up fine with the Hexagon hot end, and should mount to the x-carriage with only a few holes to be drilled.

More importantly, with some quick measurements, it would appear that one could fit two extruders back to back, and with the stock carriage, create a dual extruder set-up. Has anyone thought about this route, or have any experience with direct drive/metal extruders or dual extruder set ups?
