Minor modification from the original by Jamezracer.https://www.youmagine.com/designs/ultimaker-2-heatsink-fan-ductI rounder the outside corners to help it from curling up at the corners (through on a part this small it probably wasn't needed). Everything looks bigger on the computer screen.I also modified the air flow path to be "organic" and I removed the over hang so that this can be printed with no supports. Again, with a part this small, I don't know if it matters.I need to order longer 2.5mm screws to install this. 16mm long screws should work. Anyway, thanks to Jamezracer for this idea and posting it.https://www.youmagine.com/users/jamezracerhttps://www.youmagine.com/designs/ultimaker-2-heatsink-fan-duct#activityhttps://ultimaker.com/en/community/view/17794-detailed-documentation-of-our-hardware-and-software-mo...
