Thick paste / clay extruder

A remixed version of the clay extruder https://www.thingiverse.com/thing:1413969/
The main body was redrawn in openscad. The inner chamber was reduced in order to increase performance. The inlet was reduced to 1/2''.
The cone is used to reduce the section of the printing tip.
A joint was designed for the connection to the motor.
All parts in openscad are parametrized so it can ease the modification.
The extruder support included here is taken from the original extruder.
