This is a remix of what I thought was a clever idea, but there were a few aspects of the original I wanted to change :

• I wanted the die to be more "cubic" and less rounded
• smaller size
• didn't care for the "get the belt" on one face - made all faces NO!
• added a ! so NO wouldn't be confused with ON

Two versions are available (see print instructions).

The OnShape 3D CAD files for this are here :

Print instructions

There are two versions provided - one solid and one hollow; the hollow version prints a bit faster.

Print in PLA using the 3mf files provided; otherwise :

Solid version :

• perimeters = 2
• 10% rectilinear infill

Hollow version :

• perimeters = 3
• detect thin walls
• 0% infill

Also, do not change the orientation of the hollow die as the internal walls are filleted to enable the top surface to print properly.
