Once I noticed, that only 5015 blower isn't enough for my minis printed of PET-G and PLA, So I designed a mount for BMG + E3Dv6 direct config, where I can mount two 5015 radial blowers on both sides. For harder to melt materials, like ABS, you may use less RPM for the same result as with high RPM on single 5015. As I am using 3DTouch autoleveling sensor, I made a mount for it too.
As you want to do some edits and change something in my model, I added a source .step source.
Enjoy, post makes and remixes!
List of parts: E3Dv6 hotend; dual drive BMG extruder; NEMA17 slim motor; 4010 or 4020 fan; 2x 5015 radial fan. Also mount is compatible with e3d volcano because of moving 5015 fans and atolevelling sensor in a big range.
The BLTouch offset is 45 ; 16

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.
