3DRAG double syringe extruder

Dual syringer extruder for 3DRAG. Designed with openSCAD. The idea is to have a double syringe extruder for reactive substances (mixing) or simply a dual extruder having two syringes kept at different temperature. The jacket allows the passage of a heating or coolant liquid. All the parts were printed in ABS. If a liquid is pumped inside the jacket it's better to seal first the internal chamber by washing it with a small amount of acetone.
The project is a part of a thesis work by Giovanni Can
