The legs are 2.25″ diameter cherry with 1.5″ maple shelves and maple cross supports. The black cones and spikes are from partsexpress.
The design is more complex than it needed to be, but the adjustablity and leveling I find extreamly effective. The ‘floating’ aspect of the design is asthetic, modular and allows the shelves to expand / contract (as maple will in the climate I’m in).
There are various modifications I expect to do to make this more useful and minimize the problems inherent in this floating design. (FWIW, I don’t think I’d do another one like this.) In the meantime, however, I’m pleased with the result.
Additional (albiet poor) pictures are available for those interested. Caveat emptor… I know far more about wood than photography.
