Wide Mouth Fan Duct for Ultimaker

Wide Mouth Fan Duct for Ultimaker by owen Oct 16, 2012

Description

This delivers more air than my previous fan duct.
Suitable for V2 Nozzle.
Clearance is 3mm to platform and 2.5mm to heater block.
May be suitable for dual extruders (Untried yet)
Push on and Nut Mounted variety.
Updated Both Fan Ducts May 16/2013 (better wall thickness. Firmer fit for Push on Duct. Old one started slipping after a bit of use)
See thingiverse.com/thing:77107 for what looks to be a good improvement to my push on Duct.

Yeah I don't think air goes around corners much. It just obstructs your access to the tip. Not sure how your fans will go in series. You can drive them at half speed with M106 S128

Yep, I'll probably print another one also (bulky). I would try to mount the fans in serie (lower voltage), so as not to ask for more power from the onboard regulator.

As for the shape, I was not suggesting to reduce the opening but to round it slightly "around" the nozzle (ie. not a rectangular ie unidirectional flow). Now, the flow could get turbulent and inefficient, dunno.

I use 2 of these and operate both at 50%. I used the wide opening to let more air through and accommodate dual nozzle setups. If you try and guide the air through a small opening you get hardly anything out as these types fans can't supply air at pressure.

Instructions

Best to Print in PLA90 or ABS. This is a must if you have a heated bed.

Print either Nut Mount Duct or Push on Duct

Fan mount holes are made small so you can screw the screws straight into it without a nut too.

Careful cleaning strings around cable guide (It's a bit delicate)

My first printed version was in PLA and it did melt... while it was printing the next one in nylon! :D

So far so good. The origami stock fan duct was starting to knock my prints off the bed anyway and your design seems more efficient than many others.

I still wonder if an asymmetrical opening would cool the area around the nozzle in a more homogeneous way. I tend to reduce the fan flow with this duct as I got more distortions than before at full speed. Not sure it it is related though, b/c I started using other plastics at the same time and they could warp more than the previous ones.

works great on v2 hotend... thanks!

In my opinion the best fan duct for Ultimaker on Thingiverse.

Thanks Thingster!

This was my 2nd ever 3d print. Works perfect, prints easily. Thanks :)

Nice Work!!! Congratulations

 Thanks

Hi Owen,
Apparently I bought some odd sized fans thinking they were the same as the original ultimaker ones, I have autodesk inventor but apparently the .iam requires source files for the parts? Do advise!

Thanks =)

Hi bczd
Try the um_0000_top.zip
It contains the whole UM Model, imported from http://www.thingiverse.com/thi..., with the heater block slid down so it's more like the V2 nozzle.
Please let me know how it goes.

Great design, works really well. Printed with regular PLA no bed and no support and came out great. i did have the fan fitted for this print to ensure the print doesn't sag.

AMS3000 on Oct 24, 2012 said:

This looks great. I would love to design one for my Printrbot. Did you use a 40mm fan?

owen on Oct 25, 2012 said:

 no 50mm. You'd have to scale x and y by 80%. Not sure how the rest of it would go though.

How does regular garden variety PLA hold up?  

owen on Oct 21, 2012 said:

 I used to print with my old one at 210C which had similar clearance with no problem.
If you have a heated build platform then normal PLA is definitely no go.

laird on Oct 16, 2012 said:

Wow, that's nice. What is it designed in? Would you mind sharing the "source" file? I don't have an Ultimaker, and I'd be interested in adapting your design to my printer.

owen on Oct 16, 2012 said:

 Hi Laird, It's done in Autodesk Inventor. I tried saving it as a STEP file but it wasn't editable so I've put up the Inventor assembly file. It has other parts from the ultimaker that it references from as well.

Thanks for the new version, I was using your V1 until the V2 hotend was installed and am using a modified version of gijs's for now.   Have you tested this with a V2 hotend yet?

owen on Oct 16, 2012 said:

 Yep I'm using it on the V2 hotend.
