Remixed Escher Style Starfish Tessellation

I love the model by @RobertSoto_503356, it is a real work of art.  He mentioned that he needed to print a portion of them in TPU to do the assembly.  And they needed supports to print.

So…

I thinned the shell and filleted the edge to make it easier to assemble, and extended the base so that it can be printed without supports. The changes actually reduce the total filament needed from 4.16g with supports to 3.39g.  I was able to print and assemble an entire sphere in tricolor silk PLA without any trouble and figured it might be of use to others wanting to try it.

I got a request for an assembly video.
