I don’t remember seeing any. But you could always try messaging members here for versions of their designs with excess text taken off so you can add your own “Bonus Features” text.
Or www.fanart.tv has a lot of high-res images you could use to make your own.
Why does that website give an “unsafe” warning when you try to go to it? Looks like something to do with “HTTPS”?
Oh sorry, I think you’re right. Try https://fanart.tv/
They do have a bunch of Star Wars disc art on there. Though not sure if the image is larger than the white area on the Digistor discs I have. As I wouldn’t want there being a white border on the inside or outside of the disc.
