Ducted grill for 120mm computer fan (keep your VTX cool)
thingiverse
I needed a way to keep the VTX cool in a quadcopter whilst testing / configuring / working on it, I have a Thermaltake branded 120mm computer fan which pushes a decent amount of air, but like all computer fans the airflow from it isn't very directional. So I designed this conical-like grill which aligns the airflow into a straight, directional stream, you can easily feel the airflow 1-2 feet away. Print at 0.2mm layer height, no support necessary, about 5.5 hours print time for both pieces. Use standard computer fan screws to hold the grills in place. You can sell prints of this, but don't overcharge, and link back here. Tips are most welcome https://www.paypal.com/paypalme/Haku3D and will encourage me to make more designs for everyone to benefit.
