Moineau paste extruder

NOTE: not been tested, YET.

Updated version:
Previous version jammed as soon material entered the pump, so i geared it down. Also the coupling mechanism is different. It makes the whole thing more compact.

Rotor diameter has been doubled, inlet is redesigned. Also i designed a few moulds to make silicone sealings. One between motor and spacer, the other around the motor axis, behind the coupler and between the inlet/spacer and inlet/stator.

Vitamins:
- 4x Threaded rod M4 x 45mm
- 1x
