I think you should look at that project again. It may be possible to
disassemble the individual blocks, but it would never be taken apart at
the miters. I agree it would be a neat piece of furniture, but
precision would have to be very good to get all the blocks to fit
together perfectly.

Beat me to it! It appears that you'd simply build the individual pieces,
and then organize them any way you want. They needn't be attached, they
just stack.
