Organic Fan Guard 40mm

I designed this for the intake of my 40mm hotend cooling fan, It's the exact shape of a delta 40x40x20. The one I had was making a draft across my heated bed and causing parts to warp. The thickness forces the air to go straight in, instead of blowing out at the outer edge of the fan. There's nothing near the fan blade to cause extra noise, and it shouldn't restrict airflow at all.
This also matches my 80mm Organic Fan Guard: https://www.thingiverse.com/thing:3162175
