Part of the Tricopter series, this puzzle has 9 axes with both shallow and deep cuts.

• Inventor: David Pitcher
• Mechanism: Jumbling only axis system (edge turning triangular prism)
• Patents: Unknown
• Producer: 3D printing service
• Year: 2016
• Original Price: $0.00 USD
• Current Price: No Data

This puzzle features shallower cuts on the jumbling axes (the "S" in the name), and deep (through the origin) cuts on the non-jumbling axes (the "D" in the name). As with all the other puzzles in this series, turns can be made on either type of axis, and then subsequent turns made on the other type. However, unlike the Tricopter 9SS, once this puzzle is turned 90 degrees on a non-jumbling axis, that axis must be turned another 90 degrees before more non-jumbling turns can be made, even if other jumbling turns are made in between.
