D6 Tiles Cage
The faces have bars that divide them in a certain number of holes.
To get the result of this die, just count the number of holes between the bars on the upper face.
This die is quite big (3 x 3 x 3 cm) and the wire is 3 mm so that it should be printable in Metal.
Note that, due to its structure, this die is far from being fair (1 is more likely than 6).
