Summary

This printable extruder is intended to work on RepRap Mendel (both standard and Prusa), RepRap Huxley, and virtually any other open-source 3D printer you can find.

It features:

  1. 1.75 mm filament
  2. Adaptable mounting plate to attach it to virtually any 3D printer
  3. Very compact high-torque NEMA 11 motor
  4. Active ducted fan cooling for high reliability
  5. Wade-style hobbed bolt filament transport
  6. Wing-nut drive to spread the torque loading on the plastic gears
  7. Push-fit hot-end parts - no thread cutting
  8. Easily replaced PTFE liner for the hot end
  9. A single M3-threaded rod cut to lengths makes all the fixings
    1. Lightweight: 420g
    2. Compact design (110 mm x 90 mm x 80 mm)

I based this design (loosely) on Jstkatz's extruder (http://www.thingiverse.com/thing:7037), in particular, the idea of using a lever to trap the filament against its drive.
