The Neritic Cube is a Hexagonal Prism transformed into a cube, with two trivial tips added. The closest relative of this puzzle is the Submarine Cube. This puzzle can also be seen as a Submarine Cube with shallower cutting depths on the perpendicular axis, and this is also where its name comes from: by combining the ideas of ”shallow” and “marine”, we get the word ”neritic”.TP refer: https://twistypuzzles.com/forum/viewtopic.php?t=40412 This cube has been printed by two kinds of method & material: 1.
