Case for ZX-Key replacement keyboard, a device created by David Stevenson. http://www.zx81keyboardadventure.com/2019/02/zx-key-external-keyboard-for-zx81s-and.html If you've got a ZX81, you need one of these. David sells a really nice case on Shapeways, and for those of you who have a printer with a bed smaller than 25cm wide, I recommend buying David's design. For those of us who prefer to print our own, this is a nice alternative.
