This is a remix of a few different models that are sourced below.  I brought them together and adjusted geometry to better suit printing.  I added a different tongue to the monster D6, made the plinth a little taller as well as cut it to support a screw on top.  The idea with the top is to print the six die shapes in a clear filament/resin and run a LED through the chute in the base to a power source.  

The rocks are strategically placed to aid in printing the base without supports. I typically print all six screw on tops upside down with supports because my machine isn't great at bridging.  You might be able to pull it off with a properly tuned printer.

The “Plinth-Bottom-Spencer-Spite” STL is a special version for Spencer Crittenden's Patreon community.  He recently mailed his patrons “spite dice”, dice he determined to be karmically unbalanced and inheritly evil because either they roll poorly, or are just generally miserable in some other way.  Spencer's act of kindness in sending these out inspired me to assemble this throne, so I'm including the version with “Bespote” in the base as well as his face on the bottom.
