Fan grill for Noctua NH-L9i low profile CPU cooler

thingiverse

This is a fan grill I whipped up quick for my noctua NH-L9i low profile CPU cooler that will be used in my small form factor pc build. I figured a grill would be potentially important to keep cables from mucking up the fan in the small confined space of the small build. There are 2 files- a case, and the modifier. If you want to make things easy, just load up the case file, get rid of vertical perimeters in your slicer, and then switch to honeycomb infill and choose your preferred infill density. This will lead to the entire print being the 'grill'. What I did though is keep the vertical perimeters normal on the case stl, then load up the modifier stl in the middle of the case file as a modifier part (I did this in slic3r PE, not sure it's possible in other slicers). Then I commanded only the modifier stl to have no vertical perimeters. This leads only the circular interior to have the honeycomb pattern while everything else is solid. I did things this way rather than just design the honeycomb into the case stl itself so people could modify to their grill preference of infill type and density! You will need longer m3 screws with this added piece, so get some handy. I'm not sure what, if any, other Noctua fans this grill would fit on, let us know in the comments if it is compatible with other fans!
