Sextruder - Geared for 3mm with Nema 17 motor

Sextruder - Suspended Extruder, geared for 3mm filament with Nema 17 stepper motor.

I've been using this for a day now. Works well. Backlash with this heavy motor on top is present. Not excessive, but its there.. The total weight of the unit is 480grams, whereas s0up's suspended extruder is 220grams fully assembled with the nema11 geared motor.
