Fun Rhombic Ball Puzzle

Puzzle hints:There are many unique ways that two 4-dodecahedron parts can interlock without gaps. They can also interlock with gaps that can't be filled by neighbors. The solution does not include any gaps so these arrangements can be avoided and ignored. Rhombic dodecahedrons, in this regular/periodic array, fill space without gaps. Part of all eight 4-dodecahedron pieces are visible and their neighborhood relationships are shown. The final photo has enough information to solve the puzzle, but is still challenging. In the near future I'll post more complete piece-by-piece assembly diagrams.
