Nice.  It's a shame one can't create such lots as readily in Mathcad Prime.

Hi, Loi

 

Out of curiosity, could you produce a video of one of these cuboids rotating and passing through a hole in the other one?

 

I did have a worksheet that did that, but I've got no idea where it is now.

I think the following worksheet produced the cuboids, but I can't confirm that as I've only got Mathcad Express (which lacks programming as well as 3DPlot component that handles nested meshes).
