This unlikely tangle is actually a fair 12 sided die. This is a much more interesting shape than the traditional regular dodecahedron.
This 12 sided die is a tetragonal pentagonal dodecahedron, an isohedron. Crystallographers know it as the tetartoid. It's a challenging shape to turn into a die since opposite faces aren't even close to being parallel. To make it work, I started from a wireframe of the shape then embedded parallel sides inside it. The result is one of the most unlikely looking dice I've seen.
