E3D Chimera / Cyclops Mount w/ Servo & Cooling Fan for Prusa i3 Rework X carriage.
This is replaced w/ http://www.thingiverse.com/thing:1141659 This is my X Carriage mount for the awesome E3D Chimera / Cyclops hotend. It includes a mount for a print cooling fan as well as a Z Probe Servo mount and Z Probe arm. All STL files are netfabb fixed and print cleanly without a fan.3D printer parts and enhancements

This has been replaced with an openscad design, which is constistenly being updated. For the time being I am hosting it only at http://www.thingiverse.com/thing:1141659
I wish youmagine had an openscad customizer... I would really prefer to host it here.
This is my X Carriage mount for the awesome E3D Chimera / Cyclops hotend. It includes a mount for a print cooling fan as well as a Z Probe Servo mount and Z Probe arm. I started out with another mount but found it didn't quite fit what I was looking for. So I gutted it and built a new one using the chimera hole pattern from http://www.thingiverse.com/thing:603881. This mount adds a print cooling fan, nut traps across the board, moves the Z Probe Servo mount to a better position that doesn't interfere with X movement and centralizes the mass a bit more. This also puts the Z probe endstop switch very close to the Y and Z axis of the extruder tip.
Effective fan shroud designs is an art... I commend those of you who do it well the first time round. I currently have about 40 hours into the fan design..
UPDATE: Fan Mount 6 for 50mm fan has been added. It increases the size of the opening, less blowback and relocates the nozzle to avoid melting on the hot end. Please test it and let me know how it works.
UPDATE 2: I am working on a modification to use blower fans. First will be the 75mm x 30mm and then a 50mm x 15mm. Coming soon!
X carriage mount uses m4 screws and nuts.
Servo mount uses m3 screws and nuts.
Z Probe uses m2 screws and nuts.
All STL files are netfabb fixed and print cleanly without a fan.

This is an outdated design. That said, when I used this design, I didn't have any issues with it. This has been replaced by an openscad based design that automatically builds the parts based on what you choose for options. That does have the fan on the opposite side of one of the carriages that design supports. I would like to do the same thing with the i3 carriage and probably make that an option once at some point. That said, I've not had any issues hanging the fan off the front, other than visibility.
Aren't you worried about restricting the flow of air for the 30mm heat break fan? Perhaps mounting the print fan on the rear of the carriage would be better (as Prusa is doing in his latest design)? It would also allow you to see what is going on at the nozzles, they are hidden from view now.
