I needed a simple but effective way to control the airflow onto the CPU/GPU Heatsink of a Raspberry PI 4B. I made this to go right over them. I used a little bit of double sided tape to stick it down, and it works great.
It also has a small ring for cable management.
I printed it fan facing down, 10% infill, 80mm/s, with tree supports.
