I got this puzzle from Karl-Heinz Diekmann, who made a 3D print of it.
The puzzle works fine, but some detail adjustments had to be made:
- some silicone for the internal Mini Eastsheen 2x2x2 to improve movement
- drill-down of the surfaces of several pieces as the gaps between the puzzle pieces had been
too tight. It seems, this is not an issue of the design, but print-out tolerances.
With these adjustments the puzzle works fine now. Anyway, it should be considered to use
generic 2x2x2 mechanism of another 2x2x2 cube for the internals as the Mini Eastsheen tends to
break and needs super glue reparation. The tensions on the mini cube during the moves are quite heavy and so the small internal locking pins break easily.
Size: about 6.5cm
