That thing in the Robo3D R2 Ads

I bought a Robo3D R2 printer, and in all the pictures, it had this solid on the print bed. I was hoping that it'd be a sample print included with the printer. It wasn't. So, I spent a lot of times squinting at the picture, counting faces and observing the shape of the faces, and eventually determined that it's a Rhobic Enneacontahedron (wire frame) (wikipedia: https://en.wikipedia.org/wiki/Rhombic_enneacontahedron), which basically means a 90-faced solid where each face is a rhombus (4 sided equilateral polygon). In this case, two different sizes of Rhombii.

I went on to discover a SCAD generator at http://kitwallace.co.uk/3d/solid-index.xq?id=RhombicEnneacontahedron&mode=solid which is where I got the SCAD file from. Which leaves printing in a way that works.

The item pictured, printed at reduced speed and highest resolution available on the printer took 19 hours, but printing at lower resolution produced something in about 5 (albeit with issues). Still waiting on a weekend to blow off to print a full-sized one (190mm) as we see in the promotional pictures.
