Surprising D6 dice (now with another variant and source)

This is a pair of surprising D6 dice models:

• the original looks pretty much like a boulder or a textured sphere, but it isn't very stable on a flat surface unless it's on one of the 6 sides of the eroded cube it is “carved” from.
• the additional design is nearly the same (comes from the same OpenSCAD script), but where the original is curved, it has the un-eroded corners of the beveled cubes that make up its shape. This feels different in the hand, but has the same behavior as the original.

I figure that I should share them so tabletop gamers can surprise their friends by pulling one or two out. They're also interesting to play with.

Note that it is possible for them to end up not on one of the faces, but if there's enough energy and the surface is hard and flat, the tendency to settle on one of the 6 “sides” is very strong. If you set them down, you can get them to rest in other configurations.

The original OpenSCAD file creates it at 64mm, the other two are scaled from that model. I have only printed the 32mm STL file.  I haven't tried the 64mm version (not interested in that size for myself) and was unable to print the 24mm version because the bottom of the model makes too little contact with the build plate for my printer (an Elegoo Neptune 4 Pro) to successfully print. I include the two sizes I didn't build because someone else might want to try, but I've printed several copies of the 32mm version with no failures.

Everyone has their own preferences for printing dice that feel solid and bounce nicely when rolled; I stuck with mostly standard settings, though I recommend something like a 3D Honeycomb infill at 10%-20% when printing with PLA, 0.2mm layer height.

I have now added an STL file for the pointy (non-eroded) version and the OpenSCAD script to produce them. (By default, will produce the more sphere like original, but with a simple edit, it will produce the “pointy” version.
