This is a mount to suit a Bondtech/ V6 direct drive, incorporating a hotend shroud and duct for any 40mm axial fan.
NB. This is not compatible with the stock extruder stepper motor. You will need a pancake stepper or it'll hit the X limit switch housing.
In  response to feedback the following improvements have been implemented:
All sections of the mounting plate are thicker and stronger. There is also a clamp to secure the mounting plate to the X carriage plate, eliminating any movement due to the moment of the stepper and extruder.
The duct is now secured from both sides eliminating any twist.
The 5015 blower is now secured with both fixings.
There is a notch to accommodate the fixing lugs on the bodies of some 5015 blowers.
The BLTouch can be removed and replaced with a single bolt without disturbing the Z offset.
The effective part cooling nozzle geometry remains identical.

This Thing is work in progress. If you want to see it adapted to a specific extruder provide me with STLs of said extruder and I will look into it. If you test any of the parts please let me know of the results and print settings, I am still concerned about rigidity of some designs that include a big stepper motor so make sure to adapt your print settings (4 wall layers and 50% infill should be a good starting point).
This mount is designed to be easiliy adaptable to a variety of extruders and not to interfere with a lot of available cooling ducts. For that reason it is mounted push fit to the spacers of the V-Slot wheels and not directly to the mounting plate. If you wish you can use an additional M3 screw and washer through the mounting plate to further secure it but it has not been shown necessary in my tests yet.
Currently available:
Ender 3/CR-10 Stock extruder (not tested)
E3D Titan extruder, suitable for pancake style steppers up to 27mm as it will hit the gantry with a bigger one. (not tested)
