-| Tube
+| Main frame
-| Part where the material will flow trough. Which material should we use ? (Aluminium/ (Stainless) steel) ?
+| Main part holding all the parts together.
-Also we will have to be able to dig holes to put the temp sensors inside.
+| Done
-| Got ~1.5 m of dia. 20mm aluminum / 1.5mm thick
+| TODO
 |-
-| Auger
+| Coupler
-| Screw pushing the material
+| Holds the motor rotor and the screw together
-| Just bought [http://www.ebay.com/itm/20mm-Long-Combination-Wood-Auger-Drill-Bit-Carpenter/310775630556 one of those] on Ebay
+| '''Needs update''' with new motor rotor diameter (8mm)
 |-
-| Motor
+| Motor holder
-| Makes stuff move
+| Holds the motor (duh.)
-| http://shop.boxtec.ch/stepper-motor-with-cable-p-40933.html
+| '''Needs update''' with 3 holes mounting instead of 4. Thickness needs to be checked for usage with new motor
 |-
-| Heating element
+| Screw holder
-| Gauge 28 nichrome wire
+| Aligns the screw with the tube.
+| May need more grease to reduce friction
-Find a way to attach this (high-temp resistant tape ?) and isolate from the outside.
+| TODO
-| Bought 3.048m of G28 nichrome wire.
-|-
-| Thermometers
-| Get the internal temperature in different places of the tube (rear, middle and nose for example).
-| PT1000
-|-
-| Extrusion nozzle
-| Transforms the heated plastic into a regular filament suitable for the printer.
-| Being machined
