Redesign based on this model https://www.printables.com/es/model/161584-e3d-v6-clone-40mm-fan-mount to be able to use the following layer fan https://www.printables.com/es/model/19579-anycubic-i3-mega-ultrabase-5015-blower-turbo-fan-c 

I used an Anycubic V6 Clone with 40mm fan and 5015 layer fan.
Finally, I use this design on an Ordbot printer, but it can be used on any model with this type of hotend.
