Projection of a four-dimensional hyper cube. This was made using sage worksheet created by Edgar Bering IV in the Mathematical Computing Laboratory as a part of University of Illinois at Chicago. STL was rendered using openSCAD.

You don't necessarily need to print with support material (as shown in pictures) This needs to be scaled up, recommended at least 2000%
