Filament Fan Velocity Stack

I decided to make a little Velocity Stack for the stock Ender 3 (non pro) Filament Fan. I figured it might smooth some of the air coming in, and if not it looks interesting!

As far as I'm concerned this will only fit the 30mm filament fan on the Ender 3 or anything with the same cooling fan.

I Used Solidworks to model the part. The screw holes are larger than need be in case different hardware is used, although the stock fan screws work still.

Used PrusaSlicer V2.3.0 ; supports on base only with stack facing up. printed at 0.15mm @ 20% infill with PLA, Extruder temp: 205 Bed temp: 60
