Description

I remixed Grzybcio's excellent part cooling fan shroud (and grill) to add an integrated fan nozzle to replace the stock fan nozzle which has a tendency to droop after lots of hot (~260+°C) prints. This thing should never droop and solve that problem once and for all!

Video overview that talks about the problem it solves and why it's needed:

The image was created with Blender (I was just having some fun). You can see the real thing in the video :) EDIT: Separated the fan shroud w/nozzle and the "MK2" grill/cover into separate .stl files.  So you don't need to print the cover anymore (yeah, it's kinda ugly).

Print Settings

- Layer Height: 0.2mm

- Infill: 25% (but probably doesn't matter for this since the slicer will likely just make it 100% anyway) NOTE: This model does not need supports! It looks like it does but it does not. The one in the video was printed in Blue eSun PETG without supports just fine . The only post-processing I did was to blast it for one second with a heat gun to get rid of some stringing =)

I went through great pains to ensure this thing does not need supports. I hate supports!
