Centered Fan Nozzle

*Update 10.12.2016:

Thanks for all your downloads and prints, I am very surprised that so many people liked my design :)

On several requests i added a V2 version with a lesser angle on the back for better printing.

Have fun printing!

Will this nozzle fit on a Anet a6 printer

Jan 12, 2017 - Modified Jan 12, 2017

Why does this say "Centered" when it's left-shifted like all the old Anet nozzles? Label this noise correctly! Some of us have blowers in the correct position. The last one I looked at that said "centered" was right-shifted. WTF people?

im making a remix of this to my 3d printer (custom).
what is the recomended distance between the tip of the nozle and the bottom of the fan duct?

btw i use version 2.

for the few of us with the warping, perhaps if there was a sort of spine/ridge along the top of the ring that ran back to the rectangular duct? and also perhaps either have no gap or have the gap opposite the duct.

If I print this with ABS, will it melt when I print more with ABS?

PRINT THIS IN ABS! I printed my first one in PLA and on the next print, it melted and I could not finish the print. I had to restart everything. PRINT THIS IN ABS!

Scusate ma che ventola avete accoppiato? e che supporto ventola avete stampato?potete indicare il link di dove prendere la ventola ?grazie

Good job ^^ Thanks !

Forgive my ignorance -- what fan is this attached to (not an A8 owner, considering adapting). Thanks!

there is a second fan on the print head, a snailshell shaped squirrel cage type for cooling the filament as it exits the extruder.

I printed mine but it has small holes in the thinner walls how can I fix that?

Hey, i experienced the same with the new Cura version. i have set a wall with 1.2mm thickness with a 0.4mm nozzle on my A8 - when i change the wall size to 0.39 it works fine for me.. maybe a little workaround but i will try to fix this in a while!

I found the problem, CURAs default PLA settings use a 2.75mm Filament but mine is 1.75mm so I changed it in the CURA settings and now it should work.

Good find. I never even thought of editing the settings in Cura.

Just made the v2 one, works great and is a tight fit on the fan. Looks a little more chunky though, be warned ;)

Tip: print it in ABS because if you use PLA, when print ABS and your hotbed is at 90-100 °C, it will bend and touch the bed (ask me how I know...)

not entirely true statement :) What i mean is, when you print ABS - you dont need to cool the object so you just take the nozzle off while doing ABS.

You're right :) But for peace of mind, once you have printed it in ABS you can leave it always mounted :D

Just printing this on my A8 now :D Will share when done :) Thanks :)

I got myself an Anet A6 and i wanted to ask if the duct fits on this printer as well.

I would like to know this myself! I have an A6 as well and I'm very interested in this. Hopefully someone has tried it!

If my Printer arrives it will be the first thing i'm trying out. I will tell you if it fits or not.

That would be grand! Thank you!

improves print quality by a lot and fits perfectly
the only downside is that you cant see the nozzle printing...

so definitly a thumbs up!

Super design and function! There is only one drawback: The center nozzle obstructs most of the view to the printing object.

Yeah...downside of a cooling ring...I am printing in ABS now...so I don't even use cooling on my extruder...ABS is supposed to stay warm all the way up
