Compact Bowden Extruder

here we are !!
This is a very simple Compact Bowden Extruder for Turnigy Fabrikator ..

I used all the original elements of the printer, observed the sixth image and you can see:
-in blue, the axis
-in the red, the clamp axis
-in yellow, the washers
-in green, the bearing (13mm dia)

you just have to buy
-4 Screws M3 20 (fixing to NEMA)
-2viti M3 15 (attachment to the printer)
-Threaded Bowden Coupling 1.75 (I bought them included in E3D v6 kit)
