I really liked the idea of a fan shroud with clips so I didn't have to deal with the stock metal clips. Remixed from gretchycat's design because it closely resembled stock fan and had clips already.

Changes from the original:
- Removed the 5mm LED holders.
- Added a lip to the fan shroud that would catch on the seat sink.
- Moved the arms so the fan shroud would be positioned about 2mm higher. Fan shroud sagged below the nozzle for me in the original design.
If you don't print supports for the fan circle it could turn out a little rough (check pictures), but it still works.
Sliced in Cura 3.1.0.
Printed and tested in PLA.
Reuses original screws.
