Wide Mouth Fan Duct for Ultimaker
Description
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.

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)

This was my 2nd ever 3d print. Works perfect, prints easily. 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 =)
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.
This looks great. I would love to design one for my Printrbot. Did you use a 40mm fan?
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.
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?

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.
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.
