夏天到了，桌面上没有一个3D打印的风扇怎么 可以？因此设计了这个多功能风扇。

Summer is here, how can you not have a 3D printed fan on your desktop?

使用了常见的4090风扇，是的4090风扇不但风量大，而且噪声相对小，风的角度也很大，减少了直接吹脸的不舒服。

The common 4090 fan is used, yes, the 4090 fan not only has a large air volume, but also has relatively small noise, and the wind angle is also very large, which reduces the discomfort of blowing your face directly.

打印采用了两种颜色，包括了红色和白色，卡扣和面板使用M2的螺丝锁紧，保证了结构强度和任意悬停，在不依靠其他物品的情况下，可以非常稳定的站立。

The print is printed in two colors, including red and white, and the buckle and panel are locked with M2 screws, which ensures structural strength and can hover arbitrarily, and can stand very stably without relying on other items.

如果你的桌面没有空间摆放，你还可以挂起来这个风扇：

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

当然这个风扇是有开关的，使用了usb 5V boost到 12V（因为不是所有的USB都能提供12V电源），然后使用触摸开关实现风量调节，视频如下：

Of course, this fan has a switch, using usb 5V boost to 12V (because not all USB can provide 12V power), and then using the touch switch to adjust the air volume, the video is as follows:

希望这个风扇可以给你的夏天带来一些清凉。 Hopefully, this fan can bring some coolness to your summer.
