Why don't transform Prusa i3 Sunhokey to become a printer which can extrude pasty materials including Nutella? This kit is a remix of http://www.thingiverse.com/thing:1297 and http://www.thingiverse.com/thing:375374 that can be mounted on my designed universal X carriage for Pusua i3 Sunhokey http://www.thingiverse.com/thing:871433. The syringe can be filled with 60 cc of pasty material and it can be removed from the stand to wash it and refill. To install the kit unscrew the two rear screws of the X carriage and replace your extruder with this syringe extruder, you just need a Nema 17 step motor and a 6x18 mm threaded rod to complete this kit. It's not yet tested because is a work in progress.
