This work is based on Adrian's Geared Nema 14 extruder (Adrian's Geared Extruder) design, and includes many concepts lifted from Nophead's extruder (Nophead's Extruder Tweaks) research. More info can be found on the RepRap.org page at http://reprap.org/wiki/Wade's_Geared_Extruder and all the STL files to print your own can be found on http://www.thingiverse.com/thing:1794 or we'll print ya one!!

Each Kits comes with the following printed parts:

• 1x M8 Extruder Block
• 1X M8 Extruder Idler Block
• 1x Large Gear
• 1x Small Drive Gear

That's everything you need to get your printed parts put together; just add our NEMA17 Stepper Motor and JHead Hotend and you'll be good to go print something!! Enjoy!!

This extruder was designed for the RepRap Mendel (but will work on a Darwin or Huxley with adaptors) and is robust, provides a strong force to extrude, is cheap and DIY. It is an alternative to the standard extruder for RepRap Mendel and has the following advantages:

• no need to buy/use expensive metal gears;
  
• no need to do two precision flats on motor shaft;
  
• no need to glue the PTFE barrel;
  

Other advantages over other extruders are:

• extrude/print at high speed;
  
• good for use with a low torque/cheap Nema 17 motor ; (Needs verification)
  
• no need to use expensive and complex tools - just one hand drill, a file and a M3 tap;
  
• no need to make splines on motor shaft;
