Just creating some model in Autodesk Inventor from my inspiration about Chakana symbol. It represent the somehow the Tessaract in combination with Chakana. Ancient elders told that this is representation of 9 dimensions. The Inca believed that the Chakana was a bridge between the three worlds; the world of Gods or what we think of as Heaven, the world of Man; or Earth, and the world of the Dead; or the spiritual realm, which is why each side of the chakana is a 3-stepped pyramid. A tesseract, also known as a hypercube, is a four-dimensional cube, or, alternately, it is the extension of the idea of a square to a four-dimensional space in the same way that a cube is the extension of the idea of a square to a three-dimensional space
