TAZ Fan duct?

I have zero CAD/modeling skills, could someone PLEASE create a fan duct for the TAZ? My PLA prints will thank you immensely! :smiley:

There are already many fan ducts on Thingiverse. Oh, they changed the websiteā€™s look again, lol.

Iā€™m planning on printing this one which fits the Budaschnozzle: http://www.thingiverse.com/thing:86875

Gemini64, will that fit on the TAZ though?

Sorry, couldnā€™t say.

It sure will need a different mount though.

Mounting it seems to be the hard part.

Even with ABS, the TAZ is so fast, that it can use a fan. I had to turn on the cooling feature, to slow down the print speed whenever it does small details, otherwise it melts them.

Maybe I need to read, but enabling cooling even without a fan, will slow down the printer? Isnā€™t that the same as just slowing down the print speed? Perhaps itā€™s easier to just click the checkbox? instead of creating a different config for slic3r?

BTW this wonā€™t fit without some changesā€¦ the legs for the fan ducts have to be lengthened to clear the TAZ nozzle installation, with 1013ā€™s mods to the rear and home sensors to the left, threaded rods to the right/left.

This really needs to be designed for a front facing fan, rear facing vents and include LED lights for the nozzle at the same time.

Close, but I modeled it to the 3d files and it wonā€™t fit as is.

Yes. You need to tick ā€œEnable auto coolingā€ in Filament settings/Cooling.

Not exactly, because it adapts its speed depending on each layer. If the print time for a layer is estimated to be below 30 seconds, it will reduce speed so the layer will take 30 seconds. Thereā€™s an option to change those 30 seconds to something else.

This is great because lets say your part has a wide base but with some small projections on top of it. It will print the base at full speed but will slow down for the small projections.

Before I was having a hard time printing small things like those drawer knobs of mine. The heat would not dissipate and the parts would become a mess. Now those prints slow to a crawl but at least they come up pretty well.

There does seem to be room for a small fan on the right side of the X carriage (looking at the printer).
Or mount a squirrel cage fan somewhere, and duct it around.


I originally had a fan mount design that mounted in the backā€¦but the Z probe ended up there, so now the fan has to move.

there might be a way to just design a different mounting plate for this fan duct, since it is in 2 pieces.

Iā€™ve created a circular fan duct for the TAZ specifically. Hereā€™s the link:

Feedback and improvements would be much appreciated!

Looks really good, I look forward to seeing it in action.

I ended up getting rid of the circular part - it would sometimes dip down and damage the print and wasted bed space. My newest version doesnā€™t have either of these problems. Iā€™ve used it on my printer and it works great! (Though some have reported that on some printers, depending on fan size, it could shorten your x movement a small amount).

Iā€™m also currently working on an electronics enclosure that also fits a raspberry pi and a top-mounted spool holder.
