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 :D

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
