Best Fan Duct?

[thevictor11 0]

Hey guys, so I decided to upgrade the fan duct from the original but I'm not sure which ones are "best". I've tried a few but they've either hit the heating block or they sat too low for some reason. I have the newest Ultimaker kit with the V2 hot end and...anything else they've upgrade :lol: I've already printed a few already but it's a downer printing so many fan ducts that don't end up working and become "garbage".

I have a second fan here and a 2 pin splitter in the mail so if anyone has any suggestions on a setup for the second fan as well?

I was thinking of trying these but I figured I'd get some input before I drop more hours and resources on them.

The main reason for this upgrade is that I think the PLA warps too much if it doesn't get cooled properly which is why sometimes my nozzle catches my prints. I'm not 100% on that theory so if anyone has any input on that that'd also be great

This is the one we've been using at Ultimaker quite a bit. But mostly because it's strong and easy to print.

Thanks guys, I glad someone with more than one ultimaker replied haha. I'll give both a try tonight
