This is the Mercury DoDep 3x3x3. It is a super set of the Mercury Crazy 3x3 Plus Cube. Tom van der Zanden designed the mechanism for the Venus DoDep 3x3x3 and I've made a slight modification to his design (changing 2 pieces) to turn it into this puzzle. I've now also changed the filleting, wall thicknesses, etc to exactly match the look and feel of the other DoDep 3x3x3 puzzles, and all powder drain holes have been made tumbling friendly. This should still be considered a Tom van der Zanden design.
This puzzle requires five 16mm 3M Slotted Cheese Head screws to assemble. No other hardware is needed. You may purchase stickers for this puzzle here.
