d18 as 2dF (Double Fudge Dice In One Bipolar Die)

Double Fudge Enneagonal Trapezohedron (2-in-1 Fudge / Fate Dice)

2dF-in-1d18

The probabilities of rolling two fudge dice must be divisible by 9. This is why they are usually 2d6 because the shape is easy (cubical) and the 36 outcomes (6 squared) are divisble by 9. It is also possible to simulate this using 1 d9 inplace of both d6s... the shapeways artist magic has done just that with his D9Fudge and also clsn has done something similar with his "d9 - Two Fudge Dice in One!".

But one day I realized, 2dF could also be simulated with a single d18, using an isohedral trapezohedron shape. Since no one else had appeared to have made this design already, I set about doing it, following my philosophy of bringing the world's missing dice into reality via the wonders of 3d printing.

To achieve 4dF, simply roll two of these, available here at a discount.
