Large Volume Syringe
thingiverse
As I built a Moineau Extruder and an Oogoo Mixer/Extruder, I discovered that I required a method to supply viscous, gooey material to the extruders efficiently. Employing a medical-type syringe was not a feasible option since the outlet size was too small for genuinely viscous materials (such as peanut butter). This design addresses this specific problem.
