120mm Fan Flow Straightener, fits Bgears b-Blaster 120x38
Simply scaled down Sparrowz's 150mm fan model to a 120mm fan. The large motor hole in the center might cause weird flow on some fan but ended up being the perfect diameter for the Bgears b-Blaster 120x38 I used.

NOTE: Uploaded a made from scratch version as the scaled down version would not slice correctly with my new 0.6mm nozzle. This one has slightly thicker hex webbing and less taper to the outside but is printing fine with 0.6mm nozzle.
