Product Description
This design was inspired after my Sand Arch (which was inspired after the Jacob Hamblin Arch). It has 5 tunnels that meet at the center, and it is symetrical on both sides. If you flip it over, the tunnels become the arches and the arches become the tunnels. When 3D printed in metal, it makes a nice necklace pendant. The diameter is 1.750 inch, and the wall thickess is 0.039 inch.
