Hydra Fan Duct - 5015 35deg ducts with no 'bump'
thingiverse
These are BoothyBoothy's 5015 35 deg fan ducts for the Hydra, but with the 'bump' on the inside removed. See my comment here: https://www.thingiverse.com/thing:4062242/comments#comment-4098757 I found that bump was causing the ducts to warp (PLA) or crack (ABS) due to the stress it was putting on the very thin wall opposite. And, the fan fits very well without it, so it doesn't seem to be needed at all. Print with supports from bed only, the same as the original fan ducts.
