Dust filter for PC case CoolerMaster Silencio 650

The original dust filter caused huge airflow restriction.
My design lets much more air thru and looks nicer.

First 2 layers (0.4mm) must be printed with different settings than the rest of the model.
Here is good tutorial on how to do it in Cura https://youtu.be/su_m5zV9rvA?t=129
Recommended settings for first 2 layers:
Wall line count: 0
Top layers: 0
Bottom layers: 0
Infill line distance: 0.8mm
Infill pattern: Lines
Connect infill lines: true
