There was someone who had released a printable Whiz Wheel based on the actual tool used by the Kriegsmarine. It is a series of high-res bitmaps that you could print out and then layer them together to make a working wheel.
Fortunately for you, gutted, I have these files and have uploaded them to my FileFront account for you to download. I think it is exactly what you're looking for.
