This is much like other Penrose Voronoi projects I've done but it's one piece, not a set of tiles and was generated using a Python program and some additional steps using imagetostl.
You can read more about how I made it at this link, which includes Python code.
The easiest way to use this model is to print it at full size (10cm) to use as a coaster. it takes about 3 hours. You can scale it freely since there are no interlocking parts and I have gone down to 3cm.
Alternatively, it can be the basis of other art. I have molded it in silicone and cast in wax and resin. A model of a ring is included that you can use for making the mold. Glue the ring and the coaster to a base before filling with silicone. The ring can also be used for derived molds. I have modified the surface by casting first in paraffin and then using that to make a new mold.
Photos in order are:

coaster scaled to 3cm
resin cast with textured surface
resin cast with glossy surface
paraffin cast smoothed with heat
silicone mold coated for gloss
