Solido's "Test Part"

The SD300 has a built-in capability to build this test part. It's a geometric net of a pyramid. To conserve material, the walls are just 1 millimeter at the thickest point.


The V-shaped grooves form hinges so it can be folded, and there are flexible straps with tabs that hook the faces together. The straps rest in shallow grooves so they're flush with the faces they fold onto.


Once it's folded and hooked together, it forms a hollow pyramid 2-inches long on each edge. The faces are lustrous because they were aligned with the shiny surface of the PVC sheets the part was made from.
