6-inch 3-blade brushless fan base

I purchased a 6-inch 3-blade brushless fan head on Taobao, and upon receiving it, I discovered that the motor only has two screw holes for mounting; this accessory allows for expansion to other desktop fans to replace the original brushed motor. Note that you need to provide two screws yourself; you can refer to the hole spacing from the screenshot I got from the Taobao seller; welcome everyone to offer valuable suggestions or expand and create on your own.

I may release a complete fan model based on this analysis in the future; please stay tuned;
