***UPDATE 2/26/2018***
I have designed a 40mm fan mount to accommodate the Noctua 40mm Fan (NF-A4x10 FLX). The Noctua fan reduced the ambient noise on the CR-10S
...Show more from around 49-51 dB to around 39-40 dB. It fits snug enough, but is still free to rotate slightly around the E3D heatsink.
I printed this in NylonX for its flexibility, but I believe all materials should work as well, but I have not tested them.
Thanks to Sean for the Noctua 40mm fan shroud GrabCAD model and to JuanCR for the E3D V6 GrabCAD model!
This new mount assembly was designed to restore full use of the CR-10/CR-10S build area. I was not thrilled with the previous design which eliminated almost 15-20 mm in X and Y so I went back to re-design this unit to fit as close to the stock CR-10 extruder assembly as possible to re-gain this area back. The Z-Axis will also improve as the long E3D hotend will be closer to the bottom of the X-Axis carriage as compared to the stock assembly.
***Only Parts/Hardware needed***
Extruder mount screws for Bondtech assembly (should be included in kit)
2X M4x0.7mm x 22mm long screws for the blower fan mount

Assembly Instructions:
Mount the Bondtech Extruder Carriage part to the CR-10 X-axis carriage first. Then install the blower fan, blower fan duct, and angle brace next using the two M4 screws. This will give more room to install these components without the stepper motor getting in the way. Last step is to install the stepper motor and BondTech extruder on the mount to complete the setup. ***Make sure to orient the heat block so that the nozzle is pointing closer to the front of the mount and thermistor/heater cartridge wires are exiting toward the bondtech assembly side***
