Hi iMaterialise fans,
Offset Octa relates to Minimal Octa like Offset Hex relates to Minimal Hex. Minimal Octa is simple deep-cut spherical twisty puzzle with eight cuts. Offset Octa has the same eight cuts, but with an offset, resulting in a slightly different puzzle. The offset is possible, as the base puzzle is simple deep-cut. This enables its rails mechanism having a make and female side, and is enables offsetting to one of those sides. The geometry is closely related to Star Trap.
