This puzzle consists of a 2x2x2 twisty puzzle on the inside, and a burr puzzle outer shell. The inner 2x2x2 is only solved when the outer shell pieces fit around it. The shell pieces can also be solved separately, so this is two puzzles in one!
This puzzle is based on a mini Eastsheen 2x2x2, which you can buy
here- you will need to glue the pieces you receive from Shapeways on to one.
Please contact me to purchase one pre-assembled, or for help assembling one yourself.
