About this 3D model

The original design of the K8200 board + cover will mount the board at one side with two screws to the frame. Feels a bit fragile for my taste as I do not want to break the board accidentally. So, I've added this plate. You can use any two of the 6 holes in the middle to attach it to the frame as you like. Then, use 4 M3x12 screws plus nuts to attach the board. Finally, add the cover again. Note the two middle screes are supposed to be the weakest part in the chain - litteraly ;-)
