PLASTIC COLORS VARY.
Stewart Coffin's "Cluster Buster" puzzle made in 3 color 3D printed plastic by Pacific Puzzleworks.
This puzzle is really difficult to get apart (thus the name) because it requires pushing with six fingers in specific locations to get the pieces started sliding apart. Reassembly is quite challenging too because an awkward grip is required in order to hold each group of pieces together, and steady hands are needed in order to simultaneously align 12 pointy tips in just the right way before it’s possible to get the pieces started sliding back together again.
