The piece came together with moderate effort. An offset of 0.01″ proved to be too small for every joint. Joint incongruities were fixed using a Dremel to remove another ~0.01″ to ~0.02″ total from the top and bottom of each male element. The final product is stable and suitable for use. There are a number of improvements that can be made with an additional design iterations: the stand needs more material to eliminate minor flexing issues, larger offsets are needed for slot joints, and higher quality wood is needed to eliminate chipping in the plywood layers and improve strength and aesthetics. An alternative to the offset problem would be to surface mill the male joint elements, this would provide some improvements to overall material thickness regularity.
