This is the Mercury Uniaxial 3x3x3. It is a super set of the Mercury Crazy 3x3 Plus Cube. This is an extension of a puzzle concept I came up with on January 31, 2011 for the Deep Uniaxial 3x3x3. Tom van der Zanden designed the mechanism for the Deep Uniaxial 3x3x3 and I've made a slight modification to his design (changing only 2 pieces) to turn it into this puzzle. This should still be considered a Tom van der Zanden design.
This puzzle requires five 16mm 3M Slotted Cheese Head screws to assemble. I have purchased mine here on amazon.com. No other hardware is needed. You may purchase stickers for this puzzle here. Note this is the same sticker set used on the Deep Uniaxial 3x3x3.
