The file 'MSI B650-S Wifi I/O Sheild 3D Printer Model' is (stl) file type, size is 3.1KB.
You may need to cut off the internal corners depending on your case, I mainly designed this for my use, but since I couldn't find an STL for my specific use case I decided to post this model in hopes it would help those who can't find one either
