给我的赛车模拟器做了个2PIN风扇，使用了这款很便宜的控制器控制风速。3-12V2A可调电源适配灯带调光水泵排风扇拷贝台马达调速器3-12V1A-淘宝网   尺寸：宽50 厚31 长87
制作了这个盒子支架能把它固定在40铝型材上，使用M8x16的螺钉固定。盖子和盒体使用M3x6的螺钉固定，盒体需要使用M3铜螺母嵌入，不过我实际装上发现不需要螺钉也能固定住 :)

I made a 2PIN fan for my racing simulator and used this affordable controller to adjust the fan speed.Dimensions: 87 (L) × 50 (W) × 31 (T) mm

I crafted this box bracket to mount it on a 40-series aluminum profile, securing it with M8x16 screws. The cover and the box body are designed to fasten with M3x6 screws, which requires embedding M3 brass nuts into the box. Though in practice, I found it actually stays in place without the screws :)
