Pyramids Made from Cubes

Here are four decorative pyramids made from cubes. They are minature versions of the great pyramid at Giza. Cube_pyramid_1 is made of 472 cubes 5 mm on a side stacked so that faces touch. Cube_pyramids 2 to 4 are made from sets of overlapping cubes. Cube_pyramid_1_plus, an octahedron, is a doubled version of cube_pyramid_1. It requires support for printing. Holes at the corners and top allow the ornaments to be hung as decorations or made into mobiles. Bases can be connected together with double sided tape or wire to make octahedral ornaments. OpenSCAD code is included.
