Update 17.01.2014 - 10mm higher guide and FAN stand
X3uder is a RepRap inspired 12VDC Filament extruder. It is designed so that most parts are printable and readily available in hardware stores. The X3uder is powered by a RepRap controller and 12 VDC power supply that every user has with his 3D printer. It uses 2 x 40 watt 12 volt heating cartridges. The motor consumes between 0.5 and 3 amps, so the typical 15 amp power supply is good enough.
Design is based on different ideas from Lyman's, Filastruder and Filabot extruders.
The idea with this Filament Extruder is that when a user needs to produce some filament, he replaces the cables of his 3D printer heater output and thermistor input, connects 12vdc via a switch to the fan and motor. In this way there is no need for additional PID controllers and power supplies.
Filament production results
Production rate - 18 to 34 cm per minute of 3mm filament (depending on the plastics you are using and the extruding temperature). My tests show that 1 kg of filament is produced for about 10-12 hours.
Filament diameter tolerance - +/- 0.05 is achievable, but usually it is 0.07.
I haven't tested with 1.75 mm filament production.
List of editable TinkerCAD models (ungroup if necessary):
I am using it with a Melzi board. RAMPS MOSFETs seems to be OK too, but make sure to check that their extruder output is capable of supplying the necessary power!

Natural ABS plastic pellets
The natural ABS plastic pellets that I use are produced by LG Chem and sold in packages of 25 kg that cost 82.70 Euro (20% VAT included) - 3.3 Euro per kg (4.7 US$) !!!
The pellets are LG HF380 with MFR 43 g/10 min (220C/10kg) datasheet: http://catalog.ides.com/Datasheet.aspx?I=26793&E=15166
You can buy them from http://www.resinex.com/ if there is an office nearby - they have offices in 31 European countries.
