e3d v6 fan duct

I found this fan duct and use it with my 4028 fan~it worked good, but was too long with the e3d V6, so I made this one~
I shorter the length to fit the heater, add a stair to lean on the cooling fins which makes it much more stable~
And, I add a hole on the top to put a M3 nut which can be attached with the effector, even my 4028 can work very well with it~
Also, I leave two holes at both side, you can use ties or whatever you want to bind it on your heater~~
Hope you like it~and enjoy~
