Just a Mount to fit the e3d chimera or cyclops on a Standard prusa i3
rework x-carriage.

EDIT 02.02.2015:
-added a new Version (V2), slightly larger, added two "flaps" to get
it stiffer.

-added Version V3, like V2 with a servo holder for bed autolevel.

-for layerfan i would recommend the one from this design:

Feel free to print, try, modify

It takes 4 M4x16 screws to attach to the carriage and 3 M3x12 to
attach the hotend to the mountingplate.
