LSI 9305-16i or LSI 9305-24i fan shroud. This is a remixed design from barichardson with most overhangs removed to be more easily printed. Snaps onto the heat sink without the use of screws.
Four STL files for both the 16i and 24i with 10mm or 20mm thickness 40mm diameter fans.
For the 16i if you have bridging dialed in you may not need any supports, otherwise add a few custom supports in the fan opening. 24i will need supports for the side opening.
Rest of the part does not require any supports.
DXF and IGS files for modification included.
Also included is a version of the 16i-10mm with a surface texture applied.
