They consist of:
Lawsy's Mk4 extruder http://www.thingiverse.com/thing:47561
Some retainer for the hotend for MK4... not this http://www.thingiverse.com/thing:89216
E3D cooling fan http://www.thingiverse.com/thing:152853
My own extruder brush http://www.thingiverse.com/thing:172310

Improved plugs

I have soldered the horrible plugs as they kept losing grip of the wires... they still unplug of course.
Also i added a XT-60 plug for the fan (yeah overkill, but thats what i had laying around)

Filament spool holder

After accidentally breaking the original spool holder, and of course making some improv *flymagnet* holder i found this http://www.thingiverse.com/thing:34284
i just drilled some 3mm holes and put 2 M3x10 screws thru the back of the machine.

Thats all for now, but feel free to add more
