The 3x5x7 Fisher Cube begins with a regular 7x7x7 Cube but takes a very different path from there. Using specially designed 3D-printed extension parts and Fisher-style axes, the familiar cube is transformed into a distinctive 3x5x7 shape. The result is a puzzle that combines the complexity of a larger cube with the unusual geometry of a Fisher-style shape mod.

Once the puzzle is scrambled, its extended pieces and angled cuts make it surprisingly difficult to recognize where everything belongs. Instead of relying only on the familiar appearance of a 7x7x7, you have to pay attention to piece shapes, orientations, and how the layers interact. Every turn can make the puzzle look more confusing.

This is my version of the 3x5x7 Fisher Cube, created using 3D-printed extension parts on a regular 7x7x7 Cube. I am not the original inventor and do not know the original designer. This entry documents my build and celebrates this unusual twisty-puzzle modification.
