This is a complete direct drive print head assembly designed for the BLV mgn cube by Ben Levi. It takes inspiration from Ben's original Twin Blower but aims to make a few improvements.
My initial goal was to shorten the filament path from the extrusion gears to the nozzle but the problem is that if you want the extruder stepper motor on top of the rail (to reduce the moment force) then the original design pretty much has the extruder as close as it can be since the stepper motor cannot be lowered any further. Thus I created a completely new extruder design that flips the extruder gears below the motor gear as opposed to being position above it as in the original BMG. This brings the distance between extrusion gears and nozzle opening from ~118 mm down to ~79 mm. Whether this matters or not is up for discussion but anecdotally, I was at least able (or rather, forced) to lower my pressure advance from 0.09 to 0.06 for PETG.

I'm biased but I think it looks pretty nice!
