This guy made some Star Wars characters based on Clone Wars TV series.
He did a particular very nice work on General Grievous and Yoda, but all characters worth!
Come on, check his work.
Once inside a character page, you can check some screen shots from the 3D model and a picture of the assembled model.
And yes, you can download the model! The last link before ‘Top’ and ‘Back’ links points toward a JAR file, which contains PDO file(s) and some images.
You’ll need Pepakura Viewer in order to open PDO files.
