This Armillary Sphere was made of laser cut particle board.  We debated whether we should build the model out of wood, metal, or 3D print it, but we settled on cutting it from wood.  Once we settled on a material and method of building, we then went through several different images and models to decide how to build it.  The design we went with worked best with a solid stand that would allow the meridian to rotate between the horizon.  Next, we used Adobe Illustrator to create the rings and print the cardinal directions and degrees, which was then cut or etched into the wood by the laser cutter.  The pieces were fit together, and two nails were used to allow the globe and its parts to rotate.  The Earth is a Styrofoam ball suspended by a wooden dowel.  Once the pieces were cut, it was a matter of putting them together and making sure that the zodiac was in the correct orientation.
