I can PM you the SketchUp file. Just send me your address.
I wouldn't like to put the file on the web for now. As I started to "unmount" the model to get some pictures showing details and measures, I noticed there are a lot of problems in it. Some pieces have wrong measures, some don't align perfectly... Not a surprise, as it was the first time I ever used SketchUp.
I'll try to correct it as I go along making the detailed pictures.
The SketchUp model is still a nice help in visualizing how everthing is mounted, but for precise measurements one should refer to the Illustrator file.
