Summary

Compact (compared to Wade's) geared extruder 1:3. Large wheel has 33 teeth, small has 11. Motor size can range from Nema 17 to Nema 11.
Body_part_B_1_75mm is designed for 1.75mm filament, you have to add a 4mm OD/3mm ID PTFE tube piece.
Body_part_B_3_00mm is designed for 3mm filament, without PTFE tube.
Filament guides named "1_75" are for 1.75mm the filament version.
It allows a clear and nice view of the filament input hole. Includes a filament guide/pressure adjustment mechanism (use some glue to fix the knob to the M4 screw). You can choose four different stiffness for the piece filament_guide.
You can also choose the position of the motor: to the left or to the right.
No supports needed, the supports are included in the 3D models.
Body_part_A and body_part_B include space for extra M3 captive nuts, so you can attach your own stuff like fan ducts, leveling sensors, etc.

You will need a hobbed Drive Gear (MK7 with approx. 10.56mm effective diameter, for MK8 drive gear see: http://www.thingiverse.com/thing:1844804) and the following hardware:

2x 605 bearings
1x 623 bearing
1x M5x45mm screw, hexagonal head
1x M5 auto-locking (nylon) nut
2x M5 washers
1x M4x10mm screw, hexagonal head (knob)
1x M4 nut (knob holder)
3x M3x10mm screws (motor)
3x M3x25mm screws (assembly)
4x M3 nuts (2 assembly and 2 pinion)
1x M3 auto-locking (nylon) nut (assembly / filament guide)

P.D.: the motor in the pictures is a "pancake" nema 17 pulled from an old inkjet printer, with a torque of 12 N*cm, it gets warmer than the stronger ones but does the job.
