Plastic recycling

Description
Build an extruder to recycle and create new filament cheaply for Fixme's Ultimaker and other people's printers. An extruder is constructed from essentially two parts: a feeding mechanism, and a heater - chopped plastic is fed from a container into the feeding mechanism, which then pushes the plastic slowly through the heater to create the filament.

Goal

 * Recycle failed/old prints and extruded plastic


 * Recycle other plastics, such as PET bottles, etc
 * Experiment with new colors and materials

Obstacles

 * Get a filament of repeatable thickness


 * More complex = more difficult


 * Ventilation preferable for ABS

Extruders

 * Basic extruder

I'm guessing we should build something in between - not too simple but not too expensive either.
 * More advanced extruder

Misc

 * Color filament
 * Filament recycling detailed research paper (noskill)
 * Broyeuse extrudeuse domestique (noskill)
