Summary

Here's remixed duct for Anycubic i3 Mega. Uses standard 5015 blower fan. Clips of duct will be tight, wiggle duct while pushing on bearings.

As requested added mirrored version of cooling duct. Added also adapter for 40mm fan, design may not full fill flow technology standards, but 40mm fan can be attached :). I do recommend to use radial fan as they produce greater pressure.

Remix information will be updated later.

Edit: added mirrored version. Better to use this on stock i3 Mega.
Edit: added adapter for 40mm fan.

Print Settings

Printer:

Anycubic i3 Mega

Rafts:

No

Supports:

Yes

Resolution:

0,15

Infill:

50-70%


Notes:

If your slicer supports variable settings, you can adjust higher infill and number of shells on area of the clips. If you can't, then use 4 shell and 70% infill. ABS recommended as PLA will get soft when using duct.

Part break every time i try to mount it. Now 3rd Time. Printed in displayed orientation...

Add shells, use multiple process, if possible, so that use 100% infill on area of clips. Sand opening of clip little bit bigger and/or add some lubricant on tips of clips. You can do it!! Good Luck!!

Hey could you mod this project for v6 heating block ofcourse with v5 heatsink

Could you maybe add the CAD-Files? Like .step Files or ideally even a SolidWorks File

I really like the design. But for me it also sits a bit too low (I changed to a different nozzle, which might be a bit shorter)
Also this cooling duct restricts the usable work area, since the radial fan hits the side of the printer if you move the hotend all the way to the right. So I would like to make the radial fan off-centered. But editing .Stl files is really difficult.

So I printed this nice duct and the bottom of the print is 0.5 mm BELOW the tip of my nozzle (stock, no mods). I guess the length of the stock nozzle may differ depending on the assembly. Pity, will have to modify the stl.

Hi,
will a noctua also work as a Part cooling Fan, i heard there where some problems with the voltage?

Nice work, but I have a question. In what orientation you actualy print it? Just as shown on the first picture? I see no supports. The problem I have when I try to slice it in Cura 3.1 is with completely horizontal upper wall of the fan „mouth”. Without supports it will print in mid air, but Cura would need supports placed „everywhere”, not only „touching buildplate”. But then Cura places supports also inside the cicrular fan ducts etc. I may try to print in more verticaly, pointing straight up.

Place it like on picture. Supports only under outer corners and horizontal duct input. 45deg area does not need supports. Be careful that duct is not filled with supports :)

Thanks a lot! Is this CraftWare slicer? I use Cura and Slic3r, but they are not smart enough to allow placing suports like that.

Simplify3D ;)

I don't think cura allows selective supports? Is there a vdersion with supports you can provide? Thnaks

Can you mod this project for Sunon fan 51,7 x 51,6 x 15

Send me one.. will do then!! ;) Link?

I will receive: https://www.tme.eu/gb/details/mf50151vx-a99/dc12v-fans/sunon/mf50151vx-b00u-a99/
next week. It has same size as you linked, but greater flow and static pressure. I will take a look when I get it.

ok I am waiting for an opinion in that case

Holes were just slightly off. I used M3 screw without problems.

Damn that print looks good

Great Design,
however I would love to have a Version which can use a 40mm Fan instead?
Maybe by just adding a short "funnel"?

Hi,

Added adapter. Please, give a comment after testing. :)

what orientation did you print the 40mm fan adapter?

Do you think PETG would work for this mount?

So I installed it and the bottom of the duct is slightly below the nozzle so it just hits the print bed before the nozzle. Any suggestions?

Hi,

which hotend you have? Duct is for stock v5 or J5 hotend. Looks like heat block is very close to cooling finn, have you changed nozzle or something?

I've swapped out the hotends but it was for the spare v5 that came with the printer. Here's another pick. Is there anything I can do? Maybe loses the nozzle so it come further down?

Hmm, no idea right now. If you are on FB, there is Anycubic group and I have posted this there. Ask if othes have had issues.. None have reported though,

Love the design. Printing it out now. What's that mount and noctua fan your using for the hotend?

If you are going to print a cooling duct for your Anycubic i3 Mega, this is the one. It is the nicest I have found. (I have looked at I believe everyone of them in here) It is the simplest to install. It is a bit big on the back end but that makes it solid. Kudos to the original designer Pablo Muñoz de la Fuente for the original and Juha for the brilliant clip system.

I have asked for one request that the fan be flipped 180 to be facing down and on the left. Other than that, this is perfect.
Now just have to see about fitting a light ring.

Mirror it. You can do it in your slicer

Humm.. I dont think that will exactly work but I will try it. You may have something there. :)

I think I've spent enough hours designing it to know what I am saying.

You're a genius.. Seems to look perfect. And here is me thinking I need to convert the STL, edit it etc..
One click and it's done!! Thanks Pablo.

I have no idea how many hours you have under you. Soooo I'll give it a go. I certainly never thought it would be as simple as that. And I do appreciate the help.

Thanks for kind words. I will take a look on flipping fan around.

is it for v6 hotend or the original one? nice work

It should fit on both. I remix this to be able to use it with Titan-extruder and E3D v6 head. V6 head heat block is symmetrical, so there is more clearance. I have fitted it on my stock i3 Mega and fits well.
