This mount was designed to work for the flying bear p902 with a tevo titan extruder and a e3d v6 hotend. To cool the heatsink, you will need a 30mm fan to which you will screw onto the side. You will also have to flip the carriage around to make this fit.
As for which shroud to use, I have found that the "Blower Fan Shroud SHORT" works the best and takes up the least amount of space :) You will need 2 m4 nuts and screws to install it. To mount the shroud to the x mount, you will also need 2 m3 nuts and screws. Enjoy!
