davinci xyz printer extruder main fan housing upgrade

a better stock cooling solution
there is no reason to put a second fan on because the stock fan is sufficient if the bracket was designed properly
this is the design that should have ben on the DA vinci
if you look at the image of the stock fan mount you will see that it just blows straight against the top of the tube and not on the heat block and it is open on the sides so it blows straight and hits the other side and bounces straight back to just blow the same air out the sides of the fan
