This is a work-in-progress E3D Chimera/Cyclops mount for the Creality CR-10. It consists of a two-part mounting plate to fit ontop of the original mounting plate with three of the original M3 screws, the actual holder (one for Chimera/Cyclops and one for the stock hotend), a fan hood for the print cooling fan and two cable buide "claps" either side of the fixture which also adjust the X endstop position for the altered nozzle position.
The mount with the readily assembled heatsink/hotend/nozzle(s) setup slots into the mounting plate an can be secured with two M3x10 screws and two or four M3 nuts which press fit into the respective "sockets".
The "BackMountPlate" can be glued to the "MountWithFanShroud" by use of the also supplied "AllignmentTool" - but should not be required.
In respect to the original hotend the E3D nozzles will be a few millimeters higher, since on my CR-10 the springs are nearly fully compressed already.
