Does this fir on the Mega-S?
I'd like to use the stock fan. Would this fit?

Did anyone else found this to be too fragile as the walls are too thin?
Mine broke as I was trying to mount it on the PCB...

Did someone actually measure the temperature before and after using this? what about the chipset which is now uncooled?

I agree with you, even if the drivers will receive proper cooling I'm a little bit concerned about the lack of ventilation of the rest of the board.

I was concerned too. So I thought about it and made a remix with the end piece to have a vent that will direct the air back to the board and the chipset.

Thanks roundisfunny for the template

Anycubic i3 Mega stepper driver fan duct with chipset vent

Quick question, what size screws did you use to mount the fan? Do I need nuts on the inside or will they thread into the holes fine?

Thank you for this Thing. It looks great. How to get the vent screwed? I would like to use the 4x20 fan but I couldn't get the screws in the tube.

I have printed it without problems, but unfortunately does not fit the 32 bit board with the soldered stepper ICs so well. The duct needs to be a few mm less in width, otherwise it collides with the leftmost capacitor and the trimmer. Not sure, if the stepper driver capacitors should also be cooled? Any thoughts on this?

Nice fantube!
Would it be possible to get a two-part design - if i try to print this "tower" the upper part will shakes up and becomes crooked.
Thank you very much :)

Thank you! A wonderful solution.

is it enough cool with originals stepper drivers?

Any chance you could make a version for the 50x50 blower please?

I did a Remix design for the 50x50 blower. I'll check tonight it everything fits.

Thank you roundisfunny for the advanced design.

does this fix layer shifting with tmc2208's completely?

After this mod, is there any need of additional motherboard cooling? Since the original fan blows more all over the board.

Any chance for a 50x50 version? I already got a quiet 50x50x15 (or 12?) fan to replace the loud stock one, so it would be a shame not to use it (plus it should have more airflow than the Noctua 40x40x10).
I am using Fusion3D, so it is not easy to change it myself.

Just go over it with the program Blender (the file type)

Roundisfunny thank you so much for the remix. Printed it last night with a carbon fifer filament and turned out great. The only problem I see is that the noctua 4010 while super quiet does not move much air. Is it enough to cool all the driver fins? obviously the ones farther from the fan get hotter air and probably need more flow. Thoughts ... anybody?

My i3 Mega is printig this cool thing right now. I will try to reverse the fan. i'm thinking sucking is better then blowing the air.

All is working great :) The cooling seems to be ok. All steps are reaching the motors.

Great! Much better that my mod! Thanks!

Thanks for the update. I managed to print with cura and remove the supports. It was fiddly, but I managed.

Which slicer do you usually use which allows selective supports?

AFAIK the only slicer that allows manual placement of supports is Simplify3D.
Ever since I upgraded to the Titan extruder recently, I always get extrusion & retraction issues midway through my printing when using Cura.
With Simplify3D I get pretty much guaranteed successful prints, so it's now my default slicer.

You can also add custom support in Cura with the plugin "custom support"

Yeah, I heard it is good. If only it wasn't so expensive :(
