Hi iMaterialise fans,
Bram’s Sphere Inverted is a twisty puzzle, inspired on a geometry discovered by Bram Cohen. Bram’s Sphere has two axes, one with three turns and one with four turns. In Bram’s Sphere, the three-turn axis has the deepest cut, and the four-turn axis the shallower cut. For Bram’s Sphere Inverted, it is the opposite, and the four-turn axis has the deepest cut.
