40mm fan intake horn
thingiverse
This is a straightforward fan intake horn that enhances airflow and blocks the formation of detrimental vortices. Don't print this jet. I took some measurements and discovered it actually undermines fan performance. (But at least it still looks cool, right?) The problem lies in air guides being too close to the fan. They require a bit more space to allow for pressure dispersion. I might design a superior working model soon.
