The file 'Middleframe For STLINK-V3SET 3D Printer Model' is (stl) file type, size is 12.2KB.
This part is just a middleframe for the STLINK-V3SET as ST doesn't deliver a full closed housing for the v3 set. You can use the original top and bottom cover and the middle screw to fit everything together.
Feel free to modify, if you need one of the hidden connectors.
