The 10-11" version of this case is perfect for iPad Pro 10.5" with Zagg Slim Book for iPad Pro 5/10 When I say it fits perfectly, I mean it's not tight or loose. Even if I could custom make it, I wouldn't scale this case down even a millimeter for this purpose. The Zagg Slim Book is a great one Keyboard/case but doesn't offer adequate protection, however I think you have significant protection in this case.
