I just sat the 29cm Karlie wheel on my desk and measured the height - it's about 31.5cm high. That's leaving no room above it, and without substrate taken into account, but it should just fit in the HH if you're careful with the substrate underneath it and lift the barred part to put it in rather than manoeuvring it through the door.
I chickened out and bought the 20cm version, with a view to buying the bigger one if she needed it.
Well the 20cm is almost made for the HH cage! It fits next to the lower level, and the stand of the wheel fits nicely and tightly under the lower level, so is held in place. And it's silent! All you can hear is her feet when she is running.
