Why not use all the cases for raspberry pi 4 out there with a little modification for the minidp port? That's what I did and it is much better quality than 3D printing this one. Isn't that one of the points of making the Cool Pi 4B in the form of Raspberry Pi 4 is to use as much Raspberry Pi 4 assesscories as possible? But OK. Question for Cool Pi: What's the point of the miniDp port? Why not make 2 micro-hdmi ports like Raspberry Pi 4?

Thanks for the effort but we can't read Chinese. Does Cool Pi 4B only target Chinese users? If so, that's a pity because Cool Pi 4B is a very nice board.
