Multi-function Fan 4090(多功能风扇4090)

With summer here, how could you possibly do without a 3D-printed fan on your desktop? This versatile fan was designed for just that purpose.

A common 4090 fan is used—yes, a 4090 fan that not only produces a large volume of air but also relatively low noise and a wide wind angle, reducing the discomfort of blowing directly on your face.

Printed in two colors, red and white, the fan’s buckle and panel are secured with M2 screws, ensuring structural strength and allowing it to hover freely. It stands extremely stable without relying on any additional support.

If you don't have space on your desk, you can hang the fan:

Of course, this fan has a switch, using USB 5V boosted to 12V (not all USBs provide 12V power). The touch switch controls the fan speed. Here's a video:

Hopefully, this fan can bring some coolness to your summer.
