Modeled in Fusion 360 and then made permeable to air by modifying the models with cylinder volumes that delete the perimeter/bottom/top layers for the parts that should be porous.
The 60% gyroid infill gives a very small pore size that keeps the dust back.
I've attached the almost completely parameterized Fusion 360 file so you can change the dimensions. (You might have to manually fiddle with the ridges group)
The author marked this model as their own original creation.
