Modified Backplate for W1209 Case

I really like Mariesange's W1209 case found here:

But I wanted to directly attach it to a surface and I also realized that the soldering of my W1209 board requires more space in the case.

So I modified just the backplate to contain holes for the cable and increased the inner space. The remaining parts (front & buttons) need to be used from the original version.
